prevent boosting kprobes on exception address
Don't boost at the addresses which are listed on exception tables, because major page fault will occur on those addresses. In that case, kprobes can not ensure that when instruction buffer can be freed since some processes will sleep on the buffer. kprobes-ia64 already has same check.
