[PATCH 06/20] drm/amd/display: return correct dc_status for dcn10_validate_global

[sunpeng.li at amd.com]

From: Su Sung Chung <Su.Chung at amd.com>

[Why]
Before it was returning false in the case of failure even though return type should be enum dc_status

[How]
Return DC_FAIL_UNSUPPORTED_1 instead
