Mauro Carvalho Chehab 5eb23975b4 V4L/DVB (13846): smsdvb: Properly implement stats for both DVB and ISDB-T 
After taking a look at the driver's history and doing some tests with
DVB and ISDB-T, it was noticed that the stats were incomplete, for
ISDB-T, and weren't working for DVB.

Fixed the code and added a debug code to print the complete stats at
dmesg. This debug is useful to improve the stats of this driver.
