platform/chrome: cros_ec_sensorhub: Allocate sensorhub resource before claiming sensors
Allocate callbacks array before enumerating the sensors: The probe routine
for these sensors (for instance cros_ec_sensors_probe) can be called
within the sensorhub probe routine (cros_ec_sensors_probe())
Fixes: 145d59baff594 ("platform/chrome: cros_ec_sensorhub: Add FIFO support")
