x86/apic/vector: Handle legacy irq data correctly
The backport of upstream commit 45d55e7bac40 ("x86/apic/vector: Fix off by
one in error path") missed to fixup the legacy interrupt data which is not
longer available upstream.
Handle legacy irq data correctly by clearing the legacy storage to prevent
use after free.
Fixes: 7fd133539289 ("x86/apic/vector: Fix off by one in error path") - 4.4.y
Fixes: c557481a9491 ("x86/apic/vector: Fix off by one in error path") - 4.9.y
