drm/nouveau: add nv_encoder pointer check for NULLdrm-misc-fixes-2023-06-16
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.
