[PATCH] drm/nouveau/disp: fix an error problem in nvkm_uconn_new()

[Su Hui]

Clang Static Checker(scan-build) Warning:
drivers/gpu/drm/nouveau/nvkm/engine/disp/uconn.c:line 215, column 4
Value stored to 'ret' is never read.

Return the error code rather than zero when 'conn->info.type' has an
unknown type.

Fixes: 8b7d92cad953 ("drm/nouveau/kms/nv50-: create connectors based on nvkm 
info")
