Subject: [PATCH v2] pipe_loader_sw: Fix fd leak when instantiated via
pipe_loader_sw_probe_kms
Make pipe_loader_sw_probe_kms take ownership of the passed in fd,
like pipe_loader_drm_probe_fd does.
The only caller is dri_kms_init_screen which passes in a dupped fd,
just like dri2_init_screen passes in a dupped fd to
pipe_loader_drm_probe_fd.
