s390/sclp: use kstrobool() to parse sclp_con_drop parameter
Use kstrobool() to parse sclp_con_drop parameter. This way handling of valid values for the sclp_con_drop parameter is identical to the con3215_drop parameter. In particular this allows to pass values like "yes" and "true", which was not possible before.
