drm/amd/display: Handle virtual signal type in disable_link()
[Why]
The new implementation changed the behavior to allow process setMode
to DAL when DAL returns empty mode query for unplugged display.
This will trigger additional disable_link().
When unplug HDMI from MST dock, driver will update stream->signal to
"Virtual". disable_link() will call disable_output() if the signal type
is not DP and induce other displays on MST dock show black screen.
[How]
Don't need to process disable_output() if the signal type is virtual.
