Roger Pau Monné b5302273e2 x86/vioapic: fix usage of index in place of GSI in vioapic_write_redirent ...

The usage of idx instead of the GSI in vioapic_write_redirent when
accessing gsi_assert_count can cause a PVH dom0 with multiple
vIO-APICs to lose interrupts in case a pin of a IO-APIC different than
the first one is unmasked with pending interrupts.

Switch to use gsi instead to fix the issue.
