[PATCH AUTOSEL 5.4 6/9] drm/amdkfd: Fix pqm_destroy_queue race with GPU reset

[Sasha Levin]

From: Philip Yang <Philip.Yang at amd.com>

[ Upstream commit 7919b4cad5545ed93778f11881ceee72e4dbed66 ]

If GPU in reset, destroy_queue return -EIO, pqm_destroy_queue should
delete the queue from process_queue_list and free the resource.
