power: charger-manager: Fix checking of wrong return type
This patch fix minor issue about checking wrong return type.
The of_cm_parse_desc() return ERR_PTR(errnor number) when some error happen
in this function. But, charger_manager_probe() has only checked whether
desc is NULL or not. If of_cm_parse_desc() returns ERR_PTR(-ENOMEM), desc
isn't NULL but desc is (void *)(-ENOMEM). Althouhg some error happen for parsing
DT, charger_manager_probe() can't detect error of desc instance.
