Guan-Chun Wu 3e3f55f8b7 btree: simplify merge logic by using btree_last() return value ...

Previously btree_merge() called btree_last() only to test existence, then
performed an extra btree_lookup() to fetch the value.  This patch changes
it to directly use the value returned by btree_last(), avoiding redundant
lookups and simplifying the merge loop.
