Change uhidev(4) set/get report functions in various way.

Always pass the parent uhidev(4) descriptor corresponding to the single
USB device with multiple reportIDs instead of a child.

Make uhidev_get_report() aware of non NUL reportID by prepending a byte
to the given buffer, just like uhidev_set_report{,async}() already do.

Return the number of bytes written or read upon success and -1 otherwise.
This allow callers to deal with short reads without having do mess with
xfer error codes madness.
