drm/msm/dsi: Fix return value check for clk_get_parent
clk_get_parent returns an error pointer upon failure, not NULL. So the
checks as they exist won't catch a failure. This patch changes the
checks and the return values to properly handle an error pointer.
Fixes: c4d8cfe516dc ("drm/msm/dsi: add implementation for helper functions")
