net: af_unix can make unix_nr_socks visbile in /proc
Currently, /proc/net/protocols displays socket counts only for TCP/TCPv6
protocols
We can provide unix_nr_socks for free here, this counter being
already maintained in af_unix
Before patch :
# grep UNIX /proc/net/protocols
UNIX 428 -1 -1 NI 0 yes kernel
After patch :
# grep UNIX /proc/net/protocols
UNIX 428 98 -1 NI 0 yes kernel
