usb: gadget: f_acm: Allow restarting ACM console after stopping it
When using IOMUX, the "usbacm" console can be added/removed dynamically
from the stdout/stderr/stdin environment variables to allow temporarily
starting other USB gadgets (e.g. Fastboot).
However, right now acm_stdio_stop() does not completely undo
acm_stdio_start(): The USB gadget is unregistered, but as long as dev->priv
stays set acm_stdio_start() will never register the USB gadget again.
Clear dev->priv after we detach to make sure a start operation after a stop
operation registers the gadget again.
Fixes: fc2b399ac03b ("usb: gadget: Add CDC ACM function")
