IoStopTimer() without corresponding IoStartTimer() in usbstor\fdo.c

This module has a timer which is initialized but is not started, as the call to IoStartTimer() has been commented out.

However, there is still an active call to IoStopTimer() for that timer in USBSTOR_FdoHandlePnp() for minor function IRP_MN_STOP_DEVICE.

(This appears to be benign from looking at source code for IoStopTimer().)
