gap: Don't attempt to read the appearance if already set

Devices are unlikely to change appearance over time which is the reason
why we cache then on the storage so this skips reading it on every
reconnection.

If device is no longer exists or not paired when notifications send it
is possible to get double free and dereference of already freed memory.

To avoid this we need to recheck the state of device after sending
