perf comm: Fix comm_str__put() for reference count checking

Searching for the entry in the array needs to avoid the intermediate
pointer with reference count checking.

Refactor the array removal to binary search for the entry.

Change the array to hold an entry with a reference count (so the
intermediate pointer can work) and remove from the array when the
reference count on a comm_str falls to 1.
