usb: cdns3: remove set but not used variable 'priv_dev'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/cdns3/gadget.c: In function '__cdns3_gadget_init':
drivers/usb/cdns3/gadget.c:2665:23: warning:
 variable 'priv_dev' set but not used [-Wunused-but-set-variable]
drivers/usb/cdns3/gadget.c: In function cdns3_start_all_request:
drivers/usb/cdns3/gadget.c:357:24: warning:
 variable priv_req set but not used [-Wunused-but-set-variable]

They are never used, so can be removed.
