lsm: split the xfrm_state_alloc_security() hook implementation
The xfrm_state_alloc_security() LSM hook implementation is really a
multiplexed hook with two different behaviors depending on the
arguments passed to it by the caller. This patch splits the LSM hook
implementation into two new hook implementations, which match the
LSM hooks in the rest of the kernel:
* xfrm_state_alloc
* xfrm_state_alloc_acquire
Also included in this patch are the necessary changes to the SELinux
code; no other LSMs are affected.
