misc: Stop using getVirtProxy.

Browse Source 
The proxies are not used on the critical path, and it's usually implicit
whether they should be the FS or SE version.

Ideally in the future we won't need to worry about which version we need
to use, but the differences haven't quite been abstracted away, and
occasionally we need to decide between the two.
