usb: gadget: gadgetfs: correct dev state

This reverts commit 1826e9b1 (usb: gadget: gadgetfs: use
after free in dev_release()) and places the call to
put_dev() after setting the state.

If this is not the final call to dev_release() and the
state is not reset to STATE_DEV_DISABLED and hence all
further open() calls to the gadgetfs ep0 device will
fail with EBUSY.
