[inputs.vsphere] Panic if folder name matches name of item in folder and recursive wildcards are used

[prydin]

Version

Telegraf 1.11.7

Expected behavior:

This inventory path query for a VM should work even if a folder matches "F*": /F0/DC0/vm/**/F*

Actual behavior:

The folder is incorrectly added to the result set due to a missing type check. This subsequently causes the type coercion to the result type to fail with a panic as follows:

	panic: reflect.Set: value of type mo.Folder is not assignable to type mo.VirtualMachine

Additional info:

Note that this ONLY happens when recursive wildcards (**) are used AND the path contains a folder that matches the same pattern as the wanted object.
