qemu-iotests/109: Fix lock race condition
A race condition is currently present between the clean up attempt of the QEMU process and the execution of qemu-img. The actual (bad) output is: -Warning: Image size mismatch! -Images are identical. +qemu-img: Could not open '<build_dir>/tests/qemu-iotests/scratch/t.raw': Failed to get "consistent read" lock +Is another process using the image? A KILL signal is sent to the QEMU process, but qemu-img may begin to run before the QEMU process is really gone. qemu-img will then attempt to open the TEST_IMG file before it can secure a lock on it. This attempts a more graceful shutdown, and waits for the QEMU process to exit.
