esx: Fix esxVI_BuildSelectSet's invalid argument check
esx: Fix esxVI_BuildSelectSet's invalid argument check

The check was altered in 8c48743b9737ad4d246ab6043fd299316f9a2091
and got too strict, I've no clue how that snuck in. This check
makes every try to open a connection using the ESX driver fail
with an invalid argument error.

Revert the change to the check and add a comment to prevent future
mistakes with this check.
