Dr. David Alan Gilbert 90c647db8d Fix pflash migration
Pflash migration (e.g. q35 + EFI variable storage) fails
with the assert:

bdrv_co_do_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed.

This avoids the problem by delaying the pflash update until after
the device loads complete.

Tested by:
  Migrating Q35/EFI vm.
  Changing efi variable content (with efiboot in the guest)
  md5sum'ing the variable file before migration and after.

This is a fix that Paolo posted in the message
