radv: fix possible stack corruption
drmGetDevices2 takes count and not size. Probably hasn't caused problems yet in practice and was missed as setups with more than 8 DRM devices are not very common. Fixes: 743315f2 "radv: do not open random render node(s)" Signed-off-by: Grazvydas Ignotas <[email protected]> Reviewed-by: Bas Nieuwenhuizen <[email protected]>
