v4l2videodec: Fix activation of internal pool
If the driver does not support VIDIOC_CREATE_BUFS ioctl, the pool configuration may get changed, which requires a validation. This would fail to activate a pool in a case it shouldn't normally fail unless we are out of memory. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2677>
