dwc3: gadget: Remove WARN_ON_ONCE() from dwc3_stop_active_transfer() 



End transfer command can timeout when block reset is in progress
while handling erratic events. This dumps call stack after printing
error message for command timeout which is benign. Remove this
WARN_ON_ONCE() as error message is sufficient to debug any command
timeout.
