dwc3: gadget: Increase retry count from 500 to 3000 iterations

Browse source 
DWC3 XMIT_DEV command is timing out for USB function wakeup functionality
with current 500 iterations (i.e. timeout comes around 300us). USB DWC3
controller shall take more time to process this particular command. Hence
increase retry count from 500 to 3000 iterations (i.e same as dwc3 endpoint
command timeout value) to have sucessful USB function wakeup functionality.
