xfs: Replace xfs_isilocked with xfs_assert_ilocked
To use the new rwsem_assert_held()/rwsem_assert_held_write(), we can't
use the existing ASSERT macro. Add a new xfs_assert_ilocked() and
convert all the callers.
Fix an apparent bug in xfs_isilocked(): If the caller specifies
XFS_IOLOCK_EXCL | XFS_ILOCK_EXCL, xfs_assert_ilocked() will check both
the IOLOCK and the ILOCK are held for write. xfs_isilocked() only
checked that the ILOCK was held for write.
xfs_assert_ilocked() is always on, even if DEBUG or XFS_WARN aren't
defined. It's a cheap check, so I don't think it's worth defining
it away.
