vl: remove separate preconfig main_loop
Move post-preconfig initialization to the x-exit-preconfig. If
preconfig
is not requested, just exit preconfig mode immediately with the QMP
command.
As a result, the preconfig loop will run with accel_setup_post
and os_setup_post restrictions (xen_restrict, chroot, etc.)
already done.
