[PATCH] fw_cfg: Allow reboot-timeout=-1 again |

From: "Dr. David Alan Gilbert" <address@hidden>
Commit ee5d0f89de3e53cdb0dc added range checking on reboot-timeout
to only allow the range 0..65535; however both qemu and libvirt document
the special value -1 to mean don't reboot.
Allow it again.
Fixes: ee5d0f89de3e53cdb0dc ("fw_cfg: Fix -boot reboot-timeout error checking")
