V4L/DVB (3568d): saa7111.c fix 

When grabbing composite video with Iomega Buz, the stock driver will
prevent grabbing from the same input twice in a row, forcing the user to
switch inputs before anything useful can be grabbed again.  It is caused by
some optimization code in the input selection parts, and triggered by the
saa7111_command() executing cmd 0.  The attached patch will remedy this by
disabling cmd 0 altogether; a fix that has no found negative effects on the
rest of the code.  In fact, saa7110.c does the exact same thing.
