platform/x86: toshiba_bluetooth: Check ACPI_COMPANION() against NULL
Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device's ACPI companion object need to verify its presence. Accordingly, add a requisite ACPI_COMPANION() check against NULL to the platform/x86 toshiba_bluetooth driver.
