The main purpose of this is to allow to turn data integrity checking on and off on demand without causing interruptions. Implemented by allocating tconn->peer_integrity_tfm only when receiving a P_PROTOCOL message. l accesses to tconn->peer_integrity_tf happen in worker context, and no further synchronization is necessary. On the sender side, tconn->integrity_tfm is modified under tconn->data.mutex, and a P_PROTOCOL message is sent whenever. All accesses to tconn->integrity_tfm already happen under this mutex.
