KVM: s390: sigp: separate preparation handlers

Browse Source 
This patch introduces in preparation for further code changes separate handler
functions for:
- SIGP (RE)START - will not be allowed to terminate pending orders
- SIGP (INITIAL) CPU RESET - will be allowed to terminate certain pending orders
- unknown sigp orders

All sigp orders that require user space intervention are logged.
