[media] v4l: vb2-dma-contig: remove reference of alloc_ctx from a buffer

Browse source

This patch removes a reference to alloc_ctx from an instance of a DMA
contiguous buffer. It helps to avoid a risk of a dangling pointer if the
context is released while the buffer is still valid. Moreover it removes one
dereference step while accessing a device structure.
