virtio_net: use control_buf for coalesce params
commit accc1bf23068c1cdc4c2b015320ba856e210dd98 upstream.
Commit 699b045a8e43 ("net: virtio_net: notifications coalescing
support") added coalescing command support for virtio_net. However,
the coalesce commands are using buffers on the stack, which is causing
the device to see DMA errors. There should also be a complaint from
check_for_stack() in debug_dma_map_xyz(). Fix this by adding and using
coalesce params from the control_buf struct, which aligns with other
commands.
