[PULL V2 22/25] softmmu/runstate.c: add RunStateTransition support form COLO to PRELAUNCH |

From: Zhang Chen <chen.zhang@intel.com>
If the checkpoint occurs when the guest finishes restarting
but has not started running, the runstate_set() may reject
the transition from COLO to PRELAUNCH with the crash log:
{"timestamp": {"seconds": 1593484591, "microseconds": 26605},\
"event": "RESET", "data": {"guest": true, "reason": "guest-reset"}}
qemu-system-x86_64: invalid runstate transition: 'colo' -> 'prelaunch'
Long-term testing says that it's pretty safe.
