audio: Propagate errors from Driver::setConnectedDevices

Plumb propagation of errors reported by the implementations
of DriverInterface::setConnectedDevices up to the Module.
This allows returning the reported errors from the corresponding
IModule interface methods. Implement handling of errors
from connection state update by the Module implementation.

When updating streams about the connection status
ensure that the list of connected devices is not empty.

Also, add an extra check to AudioStreamIn#ActiveMicrophones
to validate the size of the returned active microphones
list.
