Allow nested qemu_bh_poll() after BH deletion Without this, qemu segfaults when a BH handler first deletes its BH and then calls another function which involves a nested qemu_bh_poll() call. This can be reproduced by generating an I/O error (e.g. with blkdebug) on an IDE device and using rerror/werror=stop to stop the VM. When continuing the VM, qemu segfaults.
