[PATCH] hw/intc/ioapic: Fix ACCEL_KERNEL_GSI_IRQFD_POSSIBLE typo

["Cédric Le Goater" <clg@redhat.com>]

Commit 638ac1c78457 introduced a regression in interrupt remapping
when running a VM configured with an intel-iommu device and an
assigned PCI VF. During boot, Linux reports repeated messages :

 [   15.416794] __common_interrupt: 2.37 No irq handler for vector
 [   15.417266] __common_interrupt: 2.37 No irq handler for vector
 [   15.417733] __common_interrupt: 2.37 No irq handler for vector
 [   15.418202] __common_interrupt: 2.37 No irq handler for vector
 [   15.418670] __common_interrupt: 2.37 No irq handler for vector

and may eventually hang.

The issue is caused by the incorrect use of the macro
ACCEL_KERNEL_GSI_IRQFD_POSSIBLE, which should instead be
ACCEL_GSI_IRQFD_POSSIBLE.
