[PATCH] media: fix a typo CONFIG_HAVE_GENERIC_DMA_COHERENT in videobuf2-dma-contig.c

[Prabhakar Lad <prabhakar.csengg@gmail.com>]

From: Lad, Prabhakar <prabhakar.lad@ti.com>

from commit 93049b9368a2e257ace66252ab2cc066f3399cad, which adds
a check HAVE_GENERIC_DMA_COHERENT for dma ops, the check was wrongly
made it should have been HAVE_GENERIC_DMA_COHERENT but it was
CONFIG_HAVE_GENERIC_DMA_COHERENT.
This patch fixes the typo, which was causing following build error:

videobuf2-dma-contig.c:743: error: 'vb2_dc_get_dmabuf' undeclared here (not in a function)
make[3]: *** [drivers/media/v4l2-core/videobuf2-dma-contig.o] Error 1
