jfs: Fix array index bounds check in dbAdjTree
commit c61b3e4839
upstream.
Bounds checking tools can flag a bug in dbAdjTree() for an array index
out of bounds in dmt_stree. Since dmt_stree can refer to the stree in
both structures dmaptree and dmapctl, use the larger array to eliminate
the false positive.
