Fix do_mccs parameter usage in amdgpu_dm_update_freesync_caps.
This function checks FreeSync support from the display and updates
driver state. MCCS (Monitor Control Command Set) over DDC (Display Data
Channel) is used for communication between GPU and monitor.
This changes comments but the title and the commit descriptions sound
like changing the code. Can you clarify them?
Fixes: 980a8981351a ("drm/amd/display: Avoid to do MCCS transaction if
unnecessary")
