fix race condition issue when detaching azure disk
**What this PR does / why we need it**:
add lock before detaching azure disk, without this PR, there would be lots of `Multi-Attach error` when scheduling one pod from one node to another.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#60101
**Special notes for your reviewer**:
@feiskyer @djsly @khenidak
Since we are using `getLunMutex.LockKey(instanceid)` for both AttachDisk and DetachDisk, there would be only one VM.update operation at a time for both AttachDisk and DetachDisk.
**Release note**:
```
