radv: do not open random render node(s)

drmGetDevices2() provides us with enough flexibility to build heuristics
upon. Opening a random node on the other hand will wake up the device,
regardless if it's the one we're interested or not.

v2: Rebase.
v3: Return VK_ERROR_INCOMPATIBLE_DRIVER for no devices (Ilia)
