xfs: fix deadlock in xfs_rtfree_extent
To fix the deadlock caused by repeatedly calling xfs_rtfree_extent
- removed xfs_ilock() and xfs_trans_ijoin() from xfs_rtfree_extent(),
instead added asserts that the inode is locked and has an inode_item
attached to it.
- in xfs_bunmapi() when dealing with an inode with the rt flag
call xfs_ilock() and xfs_trans_ijoin() so that the
reference count is bumped on the inode and attached it to the
transaction before calling into xfs_bmap_del_extent, similar to
what we do in xfs_bmap_rtalloc.
