Rename kvm_arch_vcpu_setup() to kvm_s390_vcpu_setup() and manually call
the new function during kvm_arch_vcpu_create(). Define an empty
kvm_arch_vcpu_setup() as it's still required for compilation. This
is effectively a nop as kvm_arch_vcpu_create() and kvm_arch_vcpu_setup()
are called back-to-back by common KVM code. Obsoleting
kvm_arch_vcpu_setup() paves the way for its removal.
Note, gmap_remove() is now called if setup fails, as s390 was previously
freeing it via kvm_arch_vcpu_destroy(), which is called by common KVM
code if kvm_arch_vcpu_setup() fails.
No functional change intended.
