     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.
