In preparation to enabling -Wvla, remove VLA. In this particular
case directly use macro NVKM_MSGQUEUE_CMDLINE_SIZE instead of local
variable cmdline_size. Also, remove cmdline_size as it is not
actually useful anymore.

I think I'd use 'sizeof (buf)' in both those lines.
Yeah. I like it.
I'll send v2 with that change shortly.
Thanks
