[PATCH] extcon: Fix return value in extcon_register_interest()

[Sachin Kamat]

Return the value obtained from extcon_find_cable_index()
instead of -ENODEV.

Fixes the following smatch info:
drivers/extcon/extcon-class.c:478 extcon_register_interest() info:
why not propagate 'obj->cable_index' from extcon_find_cable_index()
instead of -19?
