PATCH RESEND 1/1 V4L/DVB: tm6000: remove unneeded NULL check

We're testing the wrong variable here, and anyway list_entry() never returns NULL. We already verified that the list is not empty.

This was added by: 721f507b694f "V4L/DVB (12842): tm6000: avoid kernel panic while retrieving the filling buffer"
