Bluetooth: ATT: Assert if request is invalid

Browse source 
Consider invalid if the request pointer is NULL or the callback is NULL
or there is a request ongoing. This conditions would likely lead to a
crash and most likely there is some other bug involved like for example
the application queueing the same request multiple times.
