[PATCH] Re: unix_getname buglet - > 2.5.4(?)

Micheal Meeks notes:

	"Evolution is non-functioning on recent 2.5.X kernels, due to
    mal-performance in getpeername => net/unix/af_unix.c (unix_getname),
    where it seems we switch 'sk' on 'peer', but not the (previously)
    typecast pointer to it; this fixes it."

Whitespace fixes by Ray Lee.
