KVM: arm64: vgic-its: Test for valid IRQ in its_sync_lpi_pending_table()
commit 8d3a7df upstream. vgic_get_irq() may not return a valid descriptor if there is no ITS that holds a valid translation for the specified INTID. If that is the case, it is safe to silently ignore it and continue processing the LPI pending table.
