David Howells 755aedc159 iget: stop HPPFS from using iget() and read_inode() ...

Stop the HPPFS filesystem from using iget() and read_inode().  Provide an
hppfs_iget(), and call that instead of iget().  hppfs_iget() then uses
iget_locked() directly and returns a proper error code instead of an inode in
the event of an error.

hppfs_fill_sb_common() returns any error incurred when getting the root inode
instead of EINVAL.

Note that the contents of hppfs_kern.c need to be examined:

 (*) The HPPFS inode retains a pointer to the proc dentry it is shadowing, but
     whilst it does appear to retain a reference to it, it doesn't appear to
     destroy the reference if the inode goes away.

 (*) hppfs_iget() should perhaps subsume init_inode() and hppfs_read_inode().

 (*) It would appear that all hppfs inodes are the same inode because iget()
     was being called with inode number 0, which forms the lookup key.
