Ensure address-related JNI allocations are released

The Bluetooth AdapterService JNI layer relies heavily on 6-byte
address arrays. These are mapped from Java arrays via
GetByteArrayElements, but in several instances, the allocated result
is not explicitly released with ReleaseByteArrayElements.

As an initial fix, patch these callsites with the appropriate release
call. A follow-up change will refactor the way these addresses are
converted, switching instead to the lighter weight GetByteArrayRegion
alternative, avoiding allocations altogether.
