Subject: usb: gadget: net2280: restore ep_cfg after defect7374 workaround

From: Mian Yousaf Kaukab <yousaf.kaukab@intel.com>

commit 81e9d14a53eb1abfbe6ac828a87a2deb4702b5f1 upstream.

Defect 7374 workaround enables all GPEP as endpoint 0. Restore
endpoint number when defect 7374 workaround is disabled. Otherwise,
check to match USB endpoint number to hardware endpoint number in
net2280_enable() fails.
