Stanley Chang b3edc3463d extcon: realtek: add the error handler for nvmem_cell_read
There are following smatch warning:
drivers/extcon/extcon-rtk-type-c.c:905 __updated_type_c_parameter_by_efuse()
error: 'buf' dereferencing possible ERR_PTR()

The nvmem_cell_read may fail to read. So, driver must handle failure cases.
