Lukas Wunner d8bc3bf8de usb: dwc2: Drop unlock/lock upon queueing a work item

The original dwc_otg driver used a DWC_WORKQ_SCHEDULE() wrapper to queue
work items.  Because that wrapper acquired the driver's global spinlock,
an unlock/lock dance was necessary whenever a work item was queued up
while the global spinlock was already held.

The dwc2 driver dropped DWC_WORKQ_SCHEDULE() in favor of a direct call
to queue_work(), but retained the (now gratuitous) unlock/lock dance in
dwc2_handle_conn_id_status_change_intr().  Drop it.
