usb: gadged: pch_udc: get rid of redundant assignments
It seems there are leftovers of some assignments which are not used
anymore. Compiler even warns us about:
drivers/usb/gadget/udc/pch_udc.c:2022:22: warning: variable ‘dev’ set \
but not used [-Wunused-but-set-variable]
drivers/usb/gadget/udc/pch_udc.c:2639:9: warning: variable ‘ret’ set \
but not used [-Wunused-but-set-variable]
Remove them and shut compiler about.
