xfrm: store xfrm_mode directly, not its address
This structure is now only 4 bytes, so its more efficient
to cache a copy rather than its address.
No significant size difference in allmodconfig vmlinux.
With non-modular kernel that has all XFRM options enabled, this
series reduces vmlinux image size by ~11kb. All xfrm_mode
indirections are gone and all modes are built-in.
before (ipsec-next master):

after this series:
21066448 7226772 11104324 39397544 vmlinux.patched
With allmodconfig kernel, the size increase is only 362 bytes,
even all the xfrm config options removed in this series are
modular.
