include/uapi/linux/xfrm.h: Fix XFRM_MSG_MAPPING ABI breakage
Commit 2d151d39073a ("xfrm: Add possibility to set the default to block
if we have no policy") broke ABI by changing the value of the XFRM_MSG_MAPPING
enum item, thus also evading the build-time check
in security/selinux/nlmsgtab.c:selinux_nlmsg_lookup for presence of proper
security permission checks in nlmsg_xfrm_perms. Fix it by placing
XFRM_MSG_SETDEFAULT/XFRM_MSG_GETDEFAULT to the end of the enum, right before
__XFRM_MSG_MAX, and updating the nlmsg_xfrm_perms accordingly.
Fixes: 2d151d39073a ("xfrm: Add possibility to set the default to block if we have no policy")
