Natalia Petrova 1cb181271e drm/nouveau: add nv_encoder pointer check for NULL
[ Upstream commit 55b94bb8c4 ]

Pointer nv_encoder could be dereferenced at nouveau_connector.c
in case it's equal to NULL by jumping to goto label.
This patch adds a NULL-check to avoid it.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
