x86/fault: Fold smap_violation() into do_user_addr_fault()
smap_violation() has a single caller, and the contents are a bit
nonsensical. I'm going to fix it, but first let's fold it into its
caller for ease of comprehension.
In this particular case, the user_mode(regs) check is incorrect --
it will cause false positives in the case of a user-initiated
kernel-privileged access.
