[libvirt] [PATCH] Revert "Error out on missing machine type in machine configs"

[Ján Tomko]

Revert commit 55e6d8cd9eac7eb2aaa4d221585e9402cf7269d5.

It unconditionally required a machine type for all machine types
even though qemu is the only emulator using them.

Reverting this re-introduces the crash when someone fiddles with
libvirt's machine configs with /etc/, but fixes persistent domains
for other drivers.

Breaks https://bugzilla.redhat.com/show_bug.cgi?id=1267256 again.
---
A proper fix would be too invasive for the freeze, we would either
* have to revert commit f1a89a8 which relaxed the requirement
  to execute the emulator
* or (partially) revert commits a8b628e and 3d92a00 which reintroduced
  them to post parse callbacks and keep track of which parser
  requires the machine type in virDomainDefParserConfig.
