usb: gadget: pch_udc: Revert d3cb25a12138 completely
commit 50a318cc9b54a36f00beadf77e578a50f3620477 upstream.
The commit d3cb25a12138 ("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 d3cb25a12138 completely.
While at it, narrow down the scope of unlocked section to prevent
potential race when prot_stall is assigned.
Fixes: d3cb25a12138 ("usb: gadget: udc: fix spin_lock in pch_udc")
Fixes: 9903b6bedd38 ("usb: gadget: pch-udc: fix lock")
Fixes: 1d23d16a88e6 ("usb: gadget: pch_udc: reorder spin_[un]lock to avoid deadlock")
