net: Call trace_sock_exceed_buf_limit() for memcg failure with SK_MEM_RECV.
Initially, trace_sock_exceed_buf_limit() was invoked when
__sk_mem_raise_allocated() failed due to the memcg limit or the
global limit.
However, commit d6f19938eb031 ("net: expose sk wmem in
sock_exceed_buf_limit tracepoint") somehow suppressed the event
only when memcg failed to charge for SK_MEM_RECV, although the
memcg failure for SK_MEM_SEND still triggers the event.
Let's restore the event for SK_MEM_RECV.
