The dvb-usb-v2 core doesn't know anything about CI. So, the
driver needs to handle it by hand. This patch stops CI just
before stopping URB's/RC, and restarts it before URB/RC start.

It should be noticed that suspend/resume is not yet working properly,
as the PM model requires the implementation of reset_resume:
dvb_usb_az6007 1-6:1.0: no reset_resume for driver dvb_usb_az6007?
