KVM: PPC: Book3S HV nestedv2: Avoid reloading the tb offset

Browse source

The kvmppc_get_tb_offset() getter reloads KVMPPC_GSID_TB_OFFSET from the
L0 for nestedv2 host. This is unnecessary as the value does not change.
KVMPPC_GSID_TB_OFFSET also need not be reloaded in
kvmppc_{s,g}et_dec_expires().
