History
Konstantin Belousov 9eb958988a Swap order of dererencing PCPU curpmap and checking for usermode in 
trap_pfault() KPTI violation check.

EFI RT may set curpmap to NULL for the duration of the call for some
machines (PCID but no INVPCID).  Since apparently EFI RT code must be
ready for exceptions from the calls, avoid dereferencing curpmap until
we know that this call does not come from usermode.
