🌱 Revert "Replace deprecated wait functions"

[fabriziopandini]

What this PR does / why we need it:
As per comments in vmware/govmomi#3394, we are going back to use thread-safe functions task.Wait and task.WaitForResult.
Deprecation notice is going to be removed in a future version of govmomi

Still disagrees 🤔

@fabriziopandini @chrischdi Let's merge #2868 first.

Otherwise we'll have to add the nolint in this PR and need another PR after the bump to drop the nolint comments
