[media] v4l2-ioctl: log buffer type 0 correctly

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

If userspace passed the invalid buffer type 0 to the kernel, then the
kernel log would show 'type=(null)' since there was no string defined
for type 0. Fix this.
