We were trying to free a pointer into a shared buffer, which never works; and we were failing to release the buffer lock appropriately. Fix those omissions. While at it, improve documentation for brinGetTupleForHeapBlock, the inadequacy of which evidently caused these bugs in the first place. Reported independently by Zhou Digoal (bug #14668) and Alexander Sosna.
