Bhawanpreet Lakha 88fee1c900 drm/dp_mst: Don't return error code when crtc is null 
[Why]
In certain cases the crtc can be NULL and returning -EINVAL causes
atomic check to fail when it shouln't. This leads to valid
configurations failing because atomic check fails.

[How]
Don't early return if crtc is null
