staging: bcm2835_codec: Fix handling of VB2_MEMORY_DMABUF buffers

If the queue is configured as VB2_MEMORY_DMABUF then vb2_core_expbuf
fails as it ensures the queue is defined as VB2_MEMORY_MMAP.

Correct the handling so that we unmap the buffer from vcsm and the
VPU on cleanup, and then correctly get the dma buf of the new buffer.
