iommu/vt-d: Downgrade warning for pre-enabled IR
Emitting a warning is overkill in intel_setup_irq_remapping() since the
interrupt remapping is pre-enabled. For example, there's no guarantee
that kexec will explicitly disable interrupt remapping before booting a
new kernel. As a result, users are seeing warning messages like below
when they kexec boot a kernel, though there is nothing wrong:
DMAR-IR: IRQ remapping was enabled on dmar18 but we are not in kdump mode
DMAR-IR: IRQ remapping was enabled on dmar17 but we are not in kdump mode
DMAR-IR: IRQ remapping was enabled on dmar16 but we are not in kdump mode
... ...
Downgrade the severity of this message to avoid user confusion.
