x86, extable: Remove open-coded exception table entries in arch/x86/ia32/ia32entry.S

Remove open-coded exception table entries in arch/x86/ia32/ia32entry.S,
and replace them with _ASM_EXTABLE() macros; this will allow us to
change the format and type of the exception table entries.

This one was missed from the previous patch to this file.
