x86/mm: Relocate page fault error codes to traps.h

Browse source 
commit 1067f03099 upstream.

Up to this point, only fault.c used the definitions of the page fault error
codes. Thus, it made sense to keep them within such file. Other portions of
code might be interested in those definitions too. For instance, the User-
Mode Instruction Prevention emulation code will use such definitions to
emulate a page fault when it is unable to successfully copy the results
of the emulated instructions to user space.

While relocating the error code enumeration, the prefix X86_ is used to
make it consistent with the rest of the definitions in traps.h. Of course,
code using the enumeration had to be updated as well. No functional changes
were performed.
