bluetooth: Use transport array instead of hashmap for devices

Browse source 
Devices will have zero or one transports per profile, and besides the
typical lookup is also profile-based. Therefore, replace the old hashmap
(which used the transport path as key) with a simple array which holds
a transport pointer per profile.
