x86, extable: Remove open-coded exception table entries in arch/x86/lib/csum-copy_64.S

Browse source 
Remove open-coded exception table entries in arch/x86/lib/csum-copy_64.S,
and replace them with _ASM_EXTABLE() macros; this will allow us to
change the format and type of the exception table entries.
