Subject: [PATCH] net: fix a compile error when SOCK_REFCNT_DEBUG is enabled

When SOCK_REFCNT_DEBUG is enabled, below build error is met:

kernel/sysctl_binary.o: In function `sk_refcnt_debug_release':
include/net/sock.h:1025: multiple definition of `sk_refcnt_debug_release'
kernel/sysctl.o:include/net/sock.h:1025: first defined here
kernel/audit.o: In function `sk_refcnt_debug_release':
include/net/sock.h:1025: multiple definition of `sk_refcnt_debug_release'
kernel/sysctl.o:include/net/sock.h:1025: first defined here
make[1]: *** [kernel/built-in.o] Error 1
make: *** [kernel] Error 2

So we decide to make sk_refcnt_debug_release static to eliminate
the error.
