Eric Blake f61ffad53f qemu-coroutine-sleep: Silence Coverity warning ... Coverity warns that we store the address of a stack variable through a pointer passed in by the caller, which would let the caller trivially trigger use-after-free if that stored value is still present when we finish execution. However, the way coroutines work is that after our call to qemu_coroutine_yield(), control is temporarily continued in the caller prior to our function concluding, and in order to resume our coroutine, the caller must poll until the variable has been set to NULL. Thus, we can add an assert that we do not leak stack storage to the caller on function exit.
