588b65a37a vmdk: fix return values of vmdk_parent_open
While vmdk_open_desc_file (touched by the patch) correctly changed -1
to -EINVAL, vmdk_open did not.  Fix it directly in vmdk_parent_open.

34d4260e18 pc: Fix floppy drives with if=none
Commit 63ffb564 broke floppy devices specified on the command line like
-drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it
relies on drive_get() which works only with -fda/-drive if=floppy.

This patch resembles what we're already doing for IDE, i.e. remember the floppy
device that was created and use that to extract the BlockDriverStates where
needed.

8f1efd00c4 qcow2: Fix bdrv_write_compressed error handling
If during allocation of compressed clusters the cluster was already allocated
uncompressed, fail and properly release the l2_table (the latter avoids a
failed assertion).

While at it, make it return some real error numbers instead of -1.

a18e67f5f9 fdc: Fix floppy port I/O
The floppy device was broken by commit 212ec7ba (fdc: Convert to
isa_register_portio_list). While the old interface provided the port number
relative to the floppy drive's io_base, the new one provides the real port
number, so we need to apply a bitmask now to get the register number.

5cce43bb28 xen_disk: Always set feature-barrier = 1
The synchronous .bdrv_flush callback doesn't exist any more and a device really
shouldn't poke into the block layer internals anyway. All drivers are supposed
to have a correctly working bdrv_flush, so let's just hard-code this.

c76eaf1397 hw/9pfs: Fix broken compilation caused by wrong trace events
Commit c572f23a3e added trace events
with mismatching format string and arguments.

gcc reports these errors:

In file included from trace.c:2:0:
trace.h: In function ‘trace_v9fs_attach’:
trace.h:2850:9: error: too many arguments for format [-Werror=format-extra-args]
trace.h: In function ‘trace_v9fs_wstat’:
trace.h:3039:9: error: too many arguments for format [-Werror=format-extra-args]
trace.h: In function ‘trace_v9fs_mkdir’:
trace.h:3088:9: error: too many arguments for format [-Werror=format-extra-args]
trace.h: In function ‘trace_v9fs_mkdir_return’:
trace.h:3095:9: error: too many arguments for format [-Werror=format-extra-args]

Fix the format strings and also use %u instead of %d for unsigned values
in the changed strings. There are more minor errors of this kind
which I did not fix because that would make the review more difficult.

v2: Fixed position of } for v9fs_mkdir_return.
