MLK-18319-2 usb: cdns3: gadget: delete the unless code

Confirmed from CDNS, this code is from bare metal, and not needed
for Linux. Below are their response:

This is alternative deferred interrupt.
This is intended to be used in Bare Metal to not block system in
interrupt.
This was not fully checked in Linux, so we do not recommend to use it
there.
