SUNRPC: Fix null rpc_clnt dereference in rpc_task_queued tracepoint
Backchannel tasks will not have a reference to the rpc_clnt. Return -1 for
cl_clid in that case.

Subject: [PATCH 3/4] Fix: sunrpc: use signed integer for client id
Within include/linux/sunrpc/clnt.h:struct rpc_cltn, the cl_clid field
is an unsigned integer, which is the type expected by the tracepoint
signature.
However, looking into net/sunrpc/clnt.c:rpc_alloc_clid(), its allocation
considers negative signed integer as errors.
Therefore, in order to properly show "-1" in the trace output (rather
than MAX_INT) when called with a NULL task->tk_client, move to a
signed integer as backing type for the client_id field.

Subject: [PATCH 4/4] sunrpc: introduce lttng_get_clid helper
Introduce the lttng_get_clid helper to always check for NULL pointer
when getting the client id. While not always strictly needed depending
on the tracepoint callsite, prefer robustness of instrumentation and
always check for NULL rather than play whack-a-mole.
