[PATCH] drm/amd/display: remove variable active_disp

[PATCH] drm/amd/display: remove variable active_disp

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The variable active_disp is being initialized with a value that
is never read, it is being re-assigned immediately afterwards.
Clean up the code by removing the need for variable active_disp.
