Source kernel commit: 8b8ada973cacff338a0e817a97dd0afa301798c0

Stop using xfs_btree_check_lptr in xfs_btree_check_lblock_siblings,
as it only duplicates the xfs_verify_fsbno call in the other leg of
if / else besides adding a tautological level check.

With this the cur and level arguments can be removed as they are
now unused.
