[PATCH maverick, v2] UBUNTU: SAUCE: cx23885: Fix argument to videobuf_dma_unmap

[Jeremy Kerr]

BugLink: https://bugs.launchpad.net/bugs/800527

The commit bcbfc24 introduced a change to cx23885-core.c that is
incorrect - the videobuf_dma_unmap function accepts a struct videobuf *,
and bcbfc24 changed this to a struct device *.

[The videobuf_dma_unmap API has been changed, but that new API is not in
maverick]

This change reverts the call to use the correct struct videobuf *.
