Record the completion side of parameter-based control transfers when they
complete asynchronously. This lets pcap captures include descriptor
response data for requests such as GET_DESCRIPTOR from usb-host devices.

The synchronous path already recorded the completion, but the async
SETUP_STATE_PARAM path was missing it.

Tested with a usb-host HID keyboard on qemu-xhci. Before this change,
the generated pcap contained GET_DESCRIPTOR submissions but not the
corresponding completion payloads. After this change, the pcap contains
the descriptor payloads and Wireshark can associate endpoint 0x81 with
the HID interface.
