KVM: x86: Query vcpu->vcpu_idx directly and drop its accessor, again
Read vcpu->vcpu_idx directly instead of bouncing through the one-line
wrapper, kvm_vcpu_get_idx(), and drop the wrapper. The wrapper is a
remnant of the original implementation and serves no purpose; remove it
(again) before it gains more users.
kvm_vcpu_get_idx() was removed in the not-too-distant past by commit
4eeef2424153 ("KVM: x86: Query vcpu->vcpu_idx directly and drop its
accessor"), but was unintentionally re-introduced by commit a54d806688fe
("KVM: Keep memslots in tree-based structures instead of array-based ones"),
likely due to a rebase goof. The wrapper then managed to gain users in
KVM's Xen code.
No functional change intended.
