xen/spinlock: Disable IRQ spinlock (PV) allocation on PVHVM

See git commit e943bc94cb9aafe697cb00689960ab2c21061b46
(xen: disable PV spinlocks on HVM) for details.

But we did not disable it everywhere - which means that when
we boot as PVHVM we end up allocating per-CPU irq line for
spinlock. This fixes that.
