x86, extable: Remove open-coded exception table entries in arch/x86/lib/copy_user_nocache_64.S
Remove open-coded exception table entries in arch/x86/lib/copy_user_nocache_64.S,
and replace them with _ASM_EXTABLE() macros; this will allow us to
change the format and type of the exception table entries.
