INDEX_READ_MAP HAD NO MATCH If index_read_map is called for exact search and no matching records exists it will position the cursor on the next record, but still having the relative position to BTR_PCUR_ON. This will make a call for index_next to read yet another next record, instead of returning the record the cursor points to. Fixed by setting pcur->rel_pos = BTR_PCUR_BEFORE if an exact [prefix] search is done, but failed. Also avoids optimistic restoration if rel_pos != BTR_PCUR_ON, since btr_cur may be different than old_rec. rb#3324, approved by Marko and Jimmy
