Revert "usb: dwc3: fix gadget mode suspend interrupt handler issue"

This reverts portions of commit f1917115 which is commit 4e8ef34e upstream.

It is already merged into the android13-5.15 branch, in an ABI-safe way,
so revert the portion of it that added a new field as it broke the ABI
and is not needed at all.
