parisc: unwind: Replace open-coded binary search with bsearch()
There is a bug in the binary search where hi can underflow. If
addr is less than the first entry, then "hi = mid - 1" will underflow
to ULONG_MAX. Then we have an out-of-bounds read.
Replace the open-coded binary search with bsearch().
Issue found by an LLM.
