[Bluetooth] Change inquiry_cache to hci_inquiry_cache

This patch changes the inquiry_* functions to be either local to hci_core.c
or change name from inquiry_cache_lookup to hci_inquiry_cache_lookup to try
and reduce the potential for namespace conflicts. There could be USB or SCSI
or other code that uses an inquiry_cache.
