drm/amd/display: Fix crash during MPO + ODM combine mode recalculation
[Why]
When calculating recout width for an MPO plane on a mode that's using
ODM combine, driver can calculate a negative value, resulting in a
crash.
[How]
For negative widths, use zero such that validation will prune the
configuration correctly and disallow MPO.
