====================
rxrpc, afs: Miscellaneous fixes

Here are some miscellaneous fixes for rxrpc and afs:

 (1) In the rxperf test server, make it correctly receive and decode the
     terminal magic cookie.

 (2) In rxrpc, get rid of the peer->mtu_lock as it is not only redundant,
     it now causes a lockdep complaint.

 (3) In rxrpc, fix a lockdep-detected instance where a spinlock is being
     bh-locked whilst irqs are disabled.

 (4) In afs, fix the ref of a server displaced from an afs_server_list
     struct.

 (5) In afs, make afs_server records belonging to a cell take refs on the
     afs_cell record so that the latter doesn't get deleted first when that
     cell is being destroyed.
