Fixed logging in ngx_http_wait_request_handler(). If c->recv() returns 0 there is no sense in using ngx_socket_errno for logging, its value meaningless. (The code in question was copied from ngx_http_keepalive_handler(), but ngx_socket_errno makes sense there as it's used as a part of ECONNRESET handling, and the c->recv() call is preceeded by the ngx_set_socket_errno(0) call.)
