fix the windows hyperv smb synced folder creation/destruction

[rgl]

closes #12639

please note that the uac code was removed, as such, the user has to always run vagrant from an elevated shell.

I removed it because the smb share creating and removal was not working in an elevated shell.

Is removing UAC validation the best approach here? It seems like a regression;

If I understood correctly you came to the conclusion that the root cause is failed UAC prompting/alerting, were you able to track down the cause/trigger/reason?

@OnceUponALoop I was not able to track the root cause. check the related issue, it might have more clue.
