Here you return an enum value...

...and here you return an int.
It seems that the only purpose of PA_BLUETOOTH_TRANSPORT_STATE_INVALID
is to signal error from transport_state_from_string(). Since returning
-1 is the normal way to signal error, I think it's best to not have the
INVALID state at all, and just change the return value of
transport_state_from_string() to int.

If the device is dead, I suppose it should be freed after firing the
hook.
