Subject: [PATCH 5.15 083/135] drm/amdgpu: explicitly check for s0ix when evicting resources

From: Mario Limonciello <mario.limonciello@....com>

commit e53d9665ab003df0ece8f869fcd3c2bbbecf7190 upstream.

This codepath should be running in both s0ix and s3, but only does
currently because s3 and s0ix are both set in the s0ix case.
