Subject: [PATCH] xfs: fully decouple XFS_IBULK* flags from XFS_IWALK* flags

Fix up xfs_inumbers to now pass in the XFS_IBULK* flags into the flags
argument to xfs_inobt_walk, which expects the XFS_IWALK* flags.

Currently passing the wrong flags works for non-debug builds because
the only XFS_IWALK* flag has the same encoding as the corresponding
XFS_IBULK* flag, but in debug builds it can trigger an assert that no
incorrect flag is passed.  Instead just extra the relevant flag.
