[PATCH] bluetooth: Fix crash in pa_bluetooth_discovery_get_device_by_address()

[jprvita@xxxxxxxxx (jprvita@xxxxxxxxx)]

From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxx>

We need to check if d->adapter is valid before dereferencing it, and
also make sure both address strings are valid before calling pa_streq().
