After commit e2240b694a ("runtime-rs: ch: source virtio-fs queue size
from toml"), Cloud Hypervisor no longer provides fallback defaults for
virtio-fs queue configuration. When queue_size or queue_num are 0, CH
now uses those values directly instead of substituting defaults, which
causes a panic in the device manager.
The agent-ctl tool was hardcoding queue_size=0 and queue_num=0 in
share_fs_utils.rs, relying on CH's fallback behavior. This broke the
agent-api tests for Cloud Hypervisor while QEMU tests continued to pass.
Fix by reading virtio_fs_queue_size from the hypervisor config and
falling back to sensible defaults (1024 queue size, 1 queue) when not
configured, matching the previous CH default behavior.
