[PATCH] kprobes: cleanup include/asm/kprobes.h

The arch specific kprobes.h files never gets included when CONFIG_KPROBES is
turned off.  Hence check for CONFIG_KPROBES is not appropriate here in this
arch specific kprobes.h files.

Also the below defined function kprobes_exception_notify() is not needed when
CONFIG_KPROBES is off.

Compile tested for both CONFIG_KPROBES=y and N.
