During interface resume rmnet control driver submits interrupt URB only if QMI channel is opened by userspace. There is a possibility that interface is resuming from suspend and QMI channel is still not opened, in that case interrupt URB will never get submitted again. Hence always submit the interrupt URB and do not depend on if userspace has opened the QMI channel.
