spapr: Don't accidentally advertise HTM support on POWER9
Logic in spapr_populate_pa_features() enables the bit advertising
Hardware Transactional Memory (HTM) in the guest's device tree only when
KVM advertises its availability with the KVM_CAP_PPC_HTM feature.
However, this assumes that the HTM bit is off in the base template used for
the device tree value. That is true for POWER8, but not for POWER9.
It looks like that was accidentally changed in 9fb4541 "spapr: Enable ISA
3.0 MMU mode selection via CAS".
Fixes: 9fb4541f5803f8d2ba116b12113386e26482ba30
