qemuDomainChrRemove: Don't leak vmdef->consoles[0]

When removing the compat console from domain defintion, removing
it from the vmdef->consoles array is good, but not sufficient.
The console definition might have been fully allocated (after
daemon restarted and reloaded the status XML). Use
virDomainChrDefFree() to free also the definition.
