extcon: max8997: Fix return value 

Return the value obtained from the function instead of hardcoding.
Fixes the following warnings:
drivers/extcon/extcon-max8997.c:235 max8997_muic_set_path() info:
why not propagate 'ret' from max8997_update_reg() instead of (-11)?
drivers/extcon/extcon-max8997.c:248 max8997_muic_set_path() info:
why not propagate 'ret' from max8997_update_reg() instead of (-11)?
