thermal_zone_of_sensor_register is documented as returning a pointer
to either a valid thermal_zone_device on success, or a corresponding
ERR_PTR() value.
In contrast, the function returns NULL when THERMAL_OF is configured
off. Fix this.

Hi Guenter,
It was pointed out that ENOSYS is frowned upon for anything other than
indicating lack of support for a syscall. The rest of the functions in
the file use ENODEV. Updating thermal_zone_of_sensor_register to do
the same.
Could you please re-ack if you're ok with this change?
Thanks,
Punit
