[PATCH] drm/amdgpu: initialize ret in UMC error record fill

[Ruoyu Wang <ruoyuw560@gmail.com>]

umc_v12_0_fill_error_record() returns ret after walking the pages
reported by amdgpu_umc_lookup_bad_pages_in_a_row(). That helper can
return zero, including when its temporary allocation fails, leaving the
loop skipped and ret uninitialized.

Initialize ret to 0 so the zero-page path reports a deterministic status
instead of returning stack data.
