Icenowy Zheng 2c62256ca9 pipe-loader: make get_driver_descriptor() return NULL for unknown driver
Currently for unknown drivers names, get_driver_descriptor() will never
return NULL, but the driver descriptor of kmsro will be returned.
However, kmsro is meaningless when the input FD isn't a KMS-capable one.

Add the kmsro descriptor to the descriptor list, and stop to return it
for unknown names (it will still be returned for "kmsro", which the
fallback codepath in pipe_loader_drm_probe_fd_nodup() will use).
