xfs: in btree_lshift, only allocate temporary cursor when needed
We only need the temporary cursor in _btree_lshift if we're shifting
in an overlapped btree. Therefore, factor that into a single block
of code so we avoid unnecessary cursor duplication.
Also fix use of the wrong cursor when checking for corruption in
xfs_btree_rshift().
