Subject: [PATCH linux-next] drm: Remove unused variable and its assignment.

The assignment in these two places is meaningless, so it should be deleted.

The clang_analyzer complains as follows:

drivers/gpu/drm/drm_crtc_helper.c:635:2 warning:
Value stored to 'count' is never read.

drivers/gpu/drm/drm_crtc_helper.c:681:2 warning:
Value stored to 'count' is never read.
