Hexagon (target/hexagon) probe the stores in a packet at start of commit When a packet has 2 stores, either both commit or neither commit. At the beginning of gen_commit_packet, we check for multiple stores. If there are multiple stores, call a helper that will probe each of them before proceeding with the commit. Note that we don't call the probe helper for packets with only one store. Therefore, we call process_store_log before anything else involved in committing the packet. We also fix a typo in the comment in process_store_log.
