powerpc/pseries/vas: Define global hv_cop_caps struct

Browse source

The coprocessor capabilities struct is used to get default and
QoS capabilities from the hypervisor during init, DLPAR event and
migration. So instead of allocating this struct for each event,
define global struct and reuse it which allows the migration code
to avoid adding an error path.

Also disable copy/paste feature flag if any capabilities HCALL
is failed.
