Pavel Skripkin 5d8dbb7fb8 net: xfrm: fix shift-out-of-bounce 
We need to check up->dirmask to avoid shift-out-of-bounce bug,
since up->dirmask comes from userspace.

Also, added XFRM_USERPOLICY_DIRMASK_MAX constant to uapi to inform
user-space that up->dirmask has maximum possible value

Fixes: 2d151d3907 ("xfrm: Add possibility to set the default to block if we have no policy")
