[AF_UNIX]: Convert to use a spinlock instead of rwlock

From: Benjamin LaHaise <bcrl@kvack.org>

In af_unix, a rwlock is used to protect internal state.  At least on my
P4 with HT it is faster to use a spinlock due to the simpler memory
barrier used to unlock.  This patch raises bw_unix to ~690K/s.
