Subject: af_unix: Convert the unix_sk macro to an inline function for type safety

From: Aaron Conole <aconole@bytheb.org>

[ Upstream commit 4613012db1d911f80897f9446a49de817b2c4c47 ]

As suggested by Eric Dumazet this change replaces the
#define with a static inline function to enjoy
complaints by the compiler when misusing the API.
