crypto: algif_hash - Fix result clobbering in recvmsg
Recently an init call was added to hash_recvmsg so as to reset
the hash state in case a sendmsg call was never made.
Unfortunately this ended up clobbering the result if the previous
sendmsg was done with a MSG_MORE flag. This patch fixes it by
excluding that case when we make the init call.
