usb: dwc2: gadget: kill ep0 requests before reinitializing core
Make sure there are no requests pending on ep0 before reinitializing
core. Otherwise, dwc2_hsotg_enqueue_setup will fail afterwards.
Also, take hsotg->lock before calling
dwc2_hsotg_core_init_disconnected() from dwc2_conn_id_status_change()
as dwc2_hsotg_complete_request() expect lock to be held.
