We store the address of riccbd at the wrong location, overwriting
gvrd. This means that our nested guest will not be able to use runtime
instrumentation. Also, a memory leak, if our KVM guest actually sets gvrd.
Not noticed until now, as KVM guests never make use of gvrd and runtime
instrumentation wasn't completely tested yet.

KVM: s390: don't use current->thread.fpu.* when accessing registers (2016-08-25 17:33:24 +0200)
----------------------------------------------------------------
KVM: s390: Fix for fpu register errors since 4.7
This fixes a regression that was introduced by a semantic
change in commit 3f6813b9a5e0 ("s390/fpu: allocate 'struct
fpu' with the task_struct"). Symptoms are broken host userspace
fpu registers if the old FPU set/get ioctls are used.
