Davíð Steinn Geirsson 015fc393ba fix: forward CLEAR_FEATURE(ENDPOINT_HALT) to real device for host passthrough 
When a real USB device stalls an endpoint, the VM sends
CLEAR_FEATURE(ENDPOINT_HALT) to recover. Previously this was a no-op,
leaving the endpoint permanently stalled and causing the guest to hang.

Now the CLEAR_FEATURE handler in device.rs finds the interface that owns
the stalled endpoint and calls clear_halt on its handler. For host
passthrough this forwards to nusb's new Interface::clear_halt; for
simulated devices it remains a no-op.

Fixes YubiKey (and other CCID devices) hanging after endpoint stall
during passthrough.
