Daniel P. Berrangé 99a1cfc438 qemu: honour fatal errors dealing with qemu slirp helper
Currently all errors from qemuInterfacePrepareSlirp() are completely
ignored by the callers. The intention is that missing qemu-slirp binary
should cause the caller to fallback to the built-in slirp impl.

Many of the possible errors though should indeed be considered fatal.
