[PATCH 1/3] drm/amdgpu/jpeg: fix jpeg_v5_0_2_is_idle detection

From: Boyuan Zhang <[email protected]>

jpeg_v5_0_2_is_idle() initializes ret to false and then accumulates ring
idle status using &=. Since false & condition always remains false, the
function can never report the JPEG block as idle.

Initialize ret to true so the function returns true only when all JPEG
rings report RB_JOB_DONE.
