driver_vive: downgrade unknown lightcap report from error to warning

SV_ERROR with SURVIVE_ERROR_HARWARE_FAULT crashes the process when an
unrecognised USB lightcap report ID is received. New tracker firmware
routinely emits report IDs that older libsurvive versions do not know;
crashing on an unrecognised ID makes libsurvive incompatible with any
firmware newer than it was built against.

The adjacent VIVE_REPORT_USB_TRACKER_LIGHTCAP_V1 case already uses
SV_INFO and ignores the packet. Apply the same treatment to the unknown
case: log a warning and continue so tracking on all known report types
is unaffected.
