Subject: [PATCH] Fix DVB-S regression caused by a missing initialization

commit 7e0722215a510921cbb73ab4c37477d4dcb91bf8 killed
struct dvb_frontend_parameters and introduced bool re_tune
instead, but the patch missed that re_tune needs an
initialization here (previously the same effect was
reached by the params = NULL).

This patch fixes broken DVB-S support for the Hauppauge
WinTV Nova HD-S2 and similar hardware in kernel 3.3.
