V4L/DVB (13841): smsdvb: Make stats to work 

Siano series of patches seemed to cause a regression on reporting DTV
statistics. Due to that, signal indication weren't received, preventing
applications like scan to work.

Tested with ISDB-T signals and got the same scan result as with a
dib0700/dib8000 device.
