[S390] kprobes: forbid probing of stnsm/stosm/epsw

The probed instructions will be executed in a single stepped and irq
disabled context. Therefore the results of stnsm, stosm and epsw would
be wrong if probed.
So let's just disallow probing of these functions. If really needed a
fixup could be written for each of them, but I doubt it's worth it.
