drm/msm/dpu: Fix uninitialized variable

Browse source 
There is a possibility for an uninitialized *ret* variable to be
returned in some code paths.

Fix this by initializing *ret* to 0.

Addresses-Coverity-ID: 1642546 ("Uninitialized scalar variable")
Fixes: 774bcfb731 ("drm/msm/dpu: add support for virtual planes")
