contrib/qemu: disable coroutine caching in qemu
Coroutine caching in qemu is dangerous in the manner that the
qemu-block translator embeds the qemu block subsystem code. After
a graph switch, new requests can fork off and pass active graph
data structures (i.e., inodes) down into old syncenvs and old
graphs, leading to failures.
