hwmon: (occ) Fix missing newline in occ_show_extended()

In occ_show_extended() case 0, when the EXTN_FLAG_SENSOR_ID flag
is set, the sysfs_emit format string "%u" is missing the trailing
newline that the sysfs ABI expects. The else branch correctly uses
"%4phN\n", and all other show functions in this file include the
trailing newline.

Add the missing "\n" for consistency and correct sysfs output.
