Following https://golang.org/cl/291329, exitsyscall0 accesses gp.lockedm after releasing gp to the global runq. This creates a race window where another M may schedule the (unlocked) G, which subsequently calls LockOSThread, setting gp.lockedm and thus causing exitsyscall0 to think it should call stoplockedm. Avoid this race by checking if gp is locked before releasing it to the global runq.
