Nouveau - Mar 2013 - [PATCH] drm/nv50/disp: ignore encoder initialization failures

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").
