hw/arm/virt: fix GIC maintenance IRQ registration

Since commit 9036e917f8 ("{include/}hw/arm: refactor virt PPI logic"),
GIC maintenance IRQ registration fails on arm64:

[    0.979743] kvm [1]: Cannot register interrupt 9

That commit re-defined VIRTUAL_PMU_IRQ to be a INTID but missed a case
where the maintenance IRQ is actually referred by its PPI index. Just
like commit fa68ecb330db ("hw/arm/virt: fix PMU IRQ registration"), use
INITID_TO_PPI(). A search of "GIC_FDT_IRQ_TYPE_PPI" indicates that there
shouldn't be more similar issues.
