V4L/DVB: saa7115: enable anti-alias filter

This patch enables the anti-alias filter, which was originally enabled for
the saa7113, but the saa7115_init_misc was trampling the value.  Without this
patch, there would be visible vertical bands in the chroma.

Thanks to Andy Walls for helping test this change against other ivtv products.
