v4l2videodec: Increase internal bitstream pool size

Browse source 
This patch will now set the maximum of buffers to 32, allowing to grow the
pool for drivers that supports that and will respect the minimum buffers
reported by the driver. This was made to fix a stall with the virtio CODEC
driver.

Fixes #672
