s390/ctlreg: use local_ctl_load() and local_ctl_store() where possible
Convert all single control register usages of __local_ctl_load() and
__local_ctl_store() to local_ctl_load() and local_ctl_store().
This also requires to change the type of some struct lowcore members
from __u64 to unsigned long.
