s390/sclp: use kstrobool() to parse sclp_con_drop parameter

Browse Source 
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.
