powerpc/kprobes: Some minor fixes
* Mark __flush_icache_range as a function that can't be probed since its
used by the kprobe code.
* Fix an issue with single stepping and async exceptions. We need to
ensure that we dont get an async exception (external, decrementer, etc)
while we are attempting to single step the probe point.
Added a check to ensure we only handle a single step if its really
intended for the instruction in question.
