xfs: use swap macro in xfs_dir2_leafn_rebalance
Make use of the swap macro and remove unnecessary variable *tmp*. This makes the code easier to read and maintain. Also, slightly refactor some code. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Darrick J.
