rxrpc: Remove some socket lock acquire/release annotations

Remove some socket lock acquire/release annotations as lock_sock() and
release_sock() don't have them and so the checker gets confused. Removing
all of them, however, causes warnings about "context imbalance" and "wrong
count at exit" to occur instead.

Probably lock_sock() and release_sock() should have annotations on
indicating their taking of sk_lock - there is a dep_map in socket_lock_t,
but I don't know if that matters to the static checker.
