KVM: arm64: Shuffle KVM_HOST_DATA_FLAG_* indices

There's a gap in the KVM_HOST_DATA_FLAG_* indices since the removal of
KVM_HOST_DATA_FLAG_HOST_SVE_ENABLED and
KVM_HOST_DATA_FLAG_HOST_SME_ENABLED in commits:

* 459f059 ("KVM: arm64: Remove VHE host restore of CPACR_EL1.ZEN")
* 407a99c ("KVM: arm64: Remove VHE host restore of CPACR_EL1.SMEN")

Shuffle the indices to remove the gap, as Oliver requested at the time of
the removals:

There should be no functional change as a result of this patch.
