Greg Kurz 74f23d4332 spapr/xive: Configure number of servers in KVM 
The XIVE KVM devices now has an attribute to configure the number of
interrupt servers. This allows to greatly optimize the usage of the VP
space in the XIVE HW, and thus to start a lot more VMs.

Only set this attribute if available in order to support older POWER9
KVM.

The XIVE KVM device now reports the exhaustion of VPs upon the
connection of the first VCPU. Check that in order to have a chance
to provide a hint to the user.
