USB: hso: Fix OOB memory access in hso_probe/hso_get_config_data
The function hso_probe reads if_num from the USB device (as an u8) and uses
it without a length check to index an array, resulting in an OOB memory read
in hso_probe or hso_get_config_data.
Add a length check for both locations and updated hso_probe to bail on
error.
This issue has been assigned CVE-2018-19985.
