Re: [libvirt] [PATCH 1/6] conf: Remove dead code

The switch in virDomainPCIControllerModelToConnectType()
had some code that, while techically part of the
_PCIE_SWITCH_DOWNSTREAM_PORT case, was in fact dead due
to the early return.

Get rid of the dead code, and fix the inaccurate function
description while at it.

It looks like this code was added at a time when I thought that ..._LAST should be handled separately in order to catch errors where the model was improperly set to that one value, and then later I figured it was so unlikely for that to happen (vs. e.g. having it initialized to 0 and then never set) that it wasn't worth the code. So I moved the case ...._LAST: but forgot to remove the code.

Anyway, ACK.
