platform/x86: fujitsu: 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 requisite ACPI_COMPANION() checks against NULL to the
platform/x86 fujitsu-laptop driver.
