audio: don't clear output devices at standby

The output devices in adev->devices are cleared sometimes when
making a call. The sequence is as follows:

1. do_output_standby() (clears bits in adev->devices)
2. set_mode to IN_CALL state
3. select_output_device() reads the bits in adev->devices, but
   none are set.

As a result, with no valid route, call audio fails.

Fixes bug 5309421
