Fix: net: expose sk wmem in sock_exceed_buf_limit tracepoint (4.19)

See upstream commit:

    net: expose sk wmem in sock_exceed_buf_limit tracepoint

    Currently trace_sock_exceed_buf_limit() only show rmem info,
    but wmem limit may also be hit.
    So expose wmem info in this tracepoint as well.

    Regarding memcg, I think it is better to introduce a new tracepoint(if
    that is needed), i.e. trace_memcg_limit_hit other than show memcg info in
    trace_sock_exceed_buf_limit.
