virtual-device: Do not time out when waiting for SCAN command

Browse source 
The timeout is designed to continue commands automatically that are
common (e.g. opening the device). This doesn't really make sense for
scan commands, and removing the timeout enables test setups where user
interaction with the device may happen at arbitrary times.

One exception is device removal/unplug, in which case the timeout will
be added anyway.
