drm/fb-helper: Do the 'max_conn_count' zero check
Since we cannot make sure the 'max_conn_count' will always be none
zero from the users, and then if max_conn_count equals to zero, the
kcalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16).
So this patch fix this with just doing the 'max_conn_count' zero check
in the front of drm_fb_helper_init().
