media: saa7146: fix array overflow in vidioc_s_audio()
[ Upstream commit 8e4d86e241cf035d6d3467cd346e7ce490681937 ]
The "a->index" value comes from the user via the ioctl. The problem is
that the shift can wrap resulting in setting "mxb->cur_audinput" to an
invalid value, which later results in an array overflow.
