Jani Nikula 9d588f3b6f drm/crtc: fix uninitialized variable use 
[ Upstream commit 6e455f5dcdd15fa28edf0ffb5b44d3508512dccf ]

Commit 3823119b9c2b ("drm/crtc: Fix uninit-value bug in
drm_mode_setcrtc") was supposed to fix use of an uninitialized variable,
but introduced another.

num_connectors is only initialized if crtc_req->count_connectors > 0,
but it's used regardless. Fix it.

Fixes: 3823119b9c2b ("drm/crtc: Fix uninit-value bug in drm_mode_setcrtc")
