This patch introduces a dedicated work queue for handling the events from ISR (i.e. for notifying the USB device stack, for executing the enpoints callbacks, etc.). The system work queue cannot be used for this purpose as it might be used in applications for scheduling USB transfers and this could lead to a deadlock when the USB device stack would not be notified about certain event because of a system work queue item waiting for a USB transfer to be finished. The FIFO named so far `work_queue` is renamed to `usbd_evt_fifo` to better indicate its purpose and to avoid confusion. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>
