au0828: remove memset calls in v4l2 routines.
From: Devin Heitmueller <dheitmueller@linuxtv.org>
The userland callers are responsible for clearing the output buffers, so
remove the unneeded memset calls.
Thanks to Mauro Carvalho Chehab <mchehab@infradead.org> for pointing this out.
Priority: normal
