After pr #8617, create handler of containerd-shim-runc-v2 will
call handleStarted() to record the init process and handle its exit.
Init process wouldn't quit so early in normal circumstances. But if
this screnario occurs, handleStarted() will call
handleProcessExit(), which will cause deadlock because create() had
acquired s.mu, and handleProcessExit() will try to lock it again.
So, I added a parameter muLocked to handleStarted to indicate whether
or not s.mu is currently locked, and thus deciding whether or not to
lock it when calling handleProcessExit.
Fix: #9103
