x86/entry/32: Fix XEN_PV build dependency

xenpv_exc_nmi() and xenpv_exc_debug() are only defined on 64-bit kernels,
but they snuck into the 32-bit build via <asm/identry.h>, causing the link
to fail:

  ld: arch/x86/entry/entry_32.o: in function `asm_xenpv_exc_nmi':
  (.entry.text+0x817): undefined reference to `xenpv_exc_nmi'

  ld: arch/x86/entry/entry_32.o: in function `asm_xenpv_exc_debug':
  (.entry.text+0x827): undefined reference to `xenpv_exc_debug'

Only use them on 64-bit kernels.
