In its current form, xfs_isilocked() is only able to test one lock type
at a time - ilock, iolock, or mmap lock, but combinations are not
properly handled. The intent here is to check that both XFS_IOLOCK_EXCL
and XFS_ILOCK_EXCL are held, so test them each separately.
The commit ecfea3f0c8c6 ("xfs: split xfs_bmap_shift_extents") ORed the
flags together which was an error, so this patch reverts that part of
the change and check the locks independently.
