[Qemu-devel] [PULL 06/18] chardev: remove many local variables in qemu_chr_parse_socket

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

From: Daniel P. Berrangé <berrange@redhat.com>

Now that all validation is separated off into a separate method,
we can directly populate the ChardevSocket struct from the
QemuOpts values, avoiding many local variables.
