drbd: Allow to change data-integrity-alg on the fly
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.
