usb: gadget: pch_udc: Revert d3cb25a completely
commit 50a318c upstream. The commit d3cb25a ("usb: gadget: udc: fix spin_lock in pch_udc") obviously was not thought through and had made the situation even worse than it was before. Two changes after almost reverted it. but a few leftovers have been left as it. With this revert d3cb25a completely. While at it, narrow down the scope of unlocked section to prevent potential race when prot_stall is assigned.
