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. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
