media: atomisp: fix videobuf2 Kconfig depenendency

The recent conversion missed the Kconfig bit, so it can now
end up in a link error on randconfig builds:

ld.lld: error: undefined symbol: vb2_vmalloc_memops
>>> referenced by atomisp_fops.c
>>>               drivers/staging/media/atomisp/pci/atomisp_fops.o:(atomisp_open) in archive vmlinux.a
