[PATCH 1/2] drm/amd/display: Return correct error value

[mikita.lipski at amd.com]

From: Mikita Lipski <mikita.lipski at amd.com>

[why]
The function is expected to return instance of the timing generator
therefore we shouldn't be returning boolean in integer function,
and we shouldn't be returning zero so changing it to -1.
