Xu Yang 2f414a56b3 usb: roles: don't get/set_role() when usb_role_switch is unregistered 
commit b787a3e781 upstream.

There is a possibility that usb_role_switch device is unregistered before
the user put usb_role_switch. In this case, the user may still want to
get/set_role() since the user can't sense the changes of usb_role_switch.

This will add a flag to show if usb_role_switch is already registered and
avoid unwanted behaviors.

Fixes: fde0aa6c17 ("usb: common: Small class for USB role switches")
