V4L/DVB (5135): Qt1010: correct hardlockup when an app access the DVB dongle 



This patch changes qt1010.h to use dvb_usb_device struct instead of a
dvb_usb_adapter for accessing the private area of the driver.
Without this patch my PC hard locks when an application tries to access
the DVB tuner.
