[Nouveau] [PATCH] drm/nv50/disp: ignore encoder initialization failures

[Marcin Slusarz]

Nouveau does not support all encoder types, so failure to handle one should
not stop module initialization. And because of other bug, it lead to oops
in nv50_crtc_destroy (nv50_display_destroy sets nouveau_display->priv to NULL,
which is used by nv50_crtc_destroy).

Fixes regression from eb6313add6dddf07ea3e50c4caa33a9c3b2379f1
("drm/nv50: initial kms support for off-chip TMDS/DP encoders").
