[RFC] qemu_migration: Fix virConnectOpenAuth error code

[Raphael Norwitz <raphael.norwitz@xxxxxxxxxxx>]

Today if virConnectOpenAuth fails, qemuMigrationSrcPerformPeer2Peer()
returns VIR_ERR_OPERATION_FAILED. This change switches that error code
to VIR_ERR_NO_CONNECT, which is more accurate.

This should help libvirt consumers more intellegently retry migrations
on intermittent connection failures.
