Heiko Carstens 1c8b8cf28f s390/nmi: implement and use local_mcck_save() / local_mcck_restore()

Instead of using local_mcck_disable() / local_mcck_enable() implement and
use local_mcck_save() / local_mcck_restore() to disable machine checks, and
restoring the previous state.

The problem with using local_mcck_disable() / local_mcck_enable() is that
there is an assumption that machine checks are always enabled. While this
is currently the case the code still looks quite odd, readers need to
double check if the code is correct.

In order to increase readability save and then restore the old machine
check mask bit, instead of assuming that it must have been enabled.
