Simon Arlott 45145b67f5 [media] dvb-core: fix DVBFE_ALGO_HW retune bug
Commit 7e07222 breaks DVBFE_ALGO_HW tuning after a retune is requested,
which causes bad tuning on my TBS 6920.

7e0722215a [media] dvb-core: Don't pass DVBv3 parameters on tune() fops

Although re_tune is set to true when FESTATE_RETUNE occurs, it is never
set back to false which the old code used to do when !FESTATE_RETUNE.

This patch sets re_tune to false if !(state & FESTATE_RETUNE).
