KVM: SEV: Rename kvm_ghcb_get_sw_exit_code() to kvm_get_cached_sw_exit_code()
Rename kvm_ghcb_get_sw_exit_code() to kvm_get_cached_sw_exit_code() to make
it clear that KVM is getting the cached value, not reading directly from
the guest-controlled GHCB. More importantly, vacating
kvm_ghcb_get_sw_exit_code() will allow adding a KVM-specific macro-built
kvm_ghcb_get_##field() helper to read values from the GHCB.
No functional change intended.
