x86/traps: Consolidate user fixups in the #GP handler

Browse source

Move the UMIP exception fixup under the common "if (user_mode(regs))"
condition where the rest of user mode fixups reside. Also, move the UMIP
feature check into its fixup function to keep the calling code
consistent and clean.

No functional change intended.
