[libvirt] [PATCH] Fix URI connect precedence

[Martin Kletzander]

Commit abfff210 changed the order of vshParseArgv() and vshInit() in
order to make fix debugging of parameter parsing.  However, vshInit()
did a vshReconnect() even though ctl->name wasn't set according to the
'-c' parameter yet.  In order to keep both issues fixed, I've split
the vshInit() into vshInitDebug() and vshInit().

One simple memleak of ctl->name is fixed as a part of this patch,
since it is related to the issue it's fixing.
