modpost reports section mismatch errors/warnings:
WARNING: modpost: vmlinux.o: section mismatch in reference: svm_hv_hardware_setup (section: .text) -> (unknown) (section: .init.data)

WARNING: modpost: vmlinux.o: section mismatch in reference: svm_hv_hardware_setup (section: .text) -> (unknown) (section: .init.data)
Marking svm_hv_hardware_setup() as __init fixes the warnings.
I don't know why this should be needed -- it seems like a compiler
problem to me since the calling function is marked as __init.
This "(unknown) (section: .init.data)" all refer to svm_x86_ops.
Fixes: 1e0c7d40758b ("KVM: SVM: hyper-v: Remote TLB flush for SVM")

v2: also make the empty stub function be __init (Vitaly)
