rxrpc: Overhaul call refcounting

Here's a set of mostly small patches leading up to one big one.

The big patch at the end of the series overhauls how rxrpc_call refcounting
is handled, making it more sane so that calls bound to user IDs are _only_
released from socket operations or kernel API functions.  Further, the
patch stops calls from holding refs on their parent socket - which can
prevent the socket from being cleaned up.

The second largest patch improves the call tracking tracepoint by providing
extra information about the situation in which gets and puts occur.  This
allows distinctions to be drawn between refs held by the socket user ID
tree, refs held by the work queue (to be implemented by a future patch) and
other refs.

The other patches include a couple of cleanups and some simple alterations
to avoid NULL pointer dereferences in the big patch.
