This fixes a recently introduced assertion failure that was reported to happen when migrating virtio-net with a failover. The latent bug that we're executing code in coroutine context that was never supposed to run there has existed for a long time. However, the new assertion that callers of bdrv_graph_rdlock_main_loop() don't run in coroutine context makes it very visible because it's now always a crash.
