af_unix: Bulk update unix_tot_inflight/unix_inflight when queuing skb.
commit 22c3c0c52d32f41cc38cd936ea0c93f22ced3315 upstream.
Currently, we track the number of inflight sockets in two variables.
unix_tot_inflight is the total number of inflight AF_UNIX sockets on
the host, and user->unix_inflight is the number of inflight fds per
user.
We update them one by one in unix_inflight(), which can be done once
in batch. Also, sendmsg() could fail even after unix_inflight(), then
we need to acquire unix_gc_lock only to decrement the counters.
Let's bulk update the counters in unix_add_edges() and unix_del_edges(),
which is called only for successfully passed fds.
