stable inclusion from stable-v6.6.2 commit ceae60c808cc060ed428a26901972aead0513a60 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G

--------------------------------
[ Upstream commit f549a82aff57865c47b5abd17336b23cd9bb2d2c ]
In an effort to not call sof_ops_free twice, we stopped running it when probe was aborted.
Check the result of cancel_work_sync to see if this was the case.
