Bluetooth: Synchronizing access to hashmap in counter module
The hashmap access is not synchronized in counter module.
The call for hashmap free is not under motex lock. This
may lead to race condition during shut down when hash map
is being cleared while in use by another thread.
Added mutex lock for hash map free call.
