selinux: Shuffle the sk_security_struct alloc and free routines

Browse Source 
The sk_alloc_security() and sk_free_security() functions were only being
called by the selinux_sk_alloc_security() and selinux_sk_free_security()
functions so we just move the guts of the alloc/free routines to the
callers and eliminate a layer of indirection.
