spapr: Leave DR-indicator management to the guest
The DR-indicator is essentially a "virtual LED" attached to a hotpluggable device, which the guest can set to various states for the attention of the operator or management layers. It's mostly guest managed, except that we once-off set it to ACTIVE/INACTIVE in the attach/detach path. While that makes certain sense, there's no indication in PAPR that the hypervisor should do this, and the drmgr code on the guest side doesn't appear to need it (it will already set the indicator to ACTIVE on hotplug, and INACTIVE on remove). So, leave the DR-indicator entirely to the guest; the only thing we need to do is ensure it's in a sane state on reset.
