usb: Simplify imports from usb_util

The devices crate imports things from usb_util which is a separate
crate. Importing from a crate normally looks like:

    use name_of_crate::path::to::ThingToImport;

In the case it would be e.g.:

    use usb_util::hotplug::UsbHotplugHandler;

Importing these things through crate::usb::usb_util is unnecessary.

TEST=cargo check
