Joshua Aberback 079204508e drm/amd/display: Check link_active instead of lane_settings != unknown
[Why]
enable_link_dp_mst checks that cur_link_settings != unknown to determine
that the link is already enabled, to skip redundant enablement calls for
multiple streams on the same link. During dc_reinitialize_hardware,
cur_link_settings on previously-active links is not cleared, which blocks
MST links from being re-enabled after a reinitialization.

[How]
 - check for link_status->link_active instead, as it's the real intent
 - clear cur_link_settings when we clear link_active
