KVM: s390: Features and Fixes for 4.1 (kvm/next)

1. Several Fixes and enhancements
---------------------------------
- These 3 patches have cc stable:
b75f4c9 KVM: s390: Zero out current VMDB of STSI before including level3 data.
261520d KVM: s390: fix handling of write errors in the tpi handler
15462e3 KVM: s390: reinjection of irqs can fail in the tpi handler

2. SIMD support the kernel part (introduced with z13)
-----------------------------------------------------
- two KVM-generic changes in kvm.h:
1. New capability that can be enabled: KVM_CAP_S390_VECTOR_REGISTERS
2. increased padding size for sync regs in struct kvm_run to clarify that
   sync regs can be larger than 1k. This is fine as this is the last
   element in the structure.
