When booting a new non-kdump kernel, we have below failure message:

[    0.004000] DMAR-IR: IRQ remapping was enabled on dmar2 but we are not in kdump mode
[    0.004000] DMAR-IR: Failed to copy IR table for dmar2 from previous kernel
[    0.004000] DMAR-IR: IRQ remapping was enabled on dmar1 but we are not in kdump mode
[    0.004000] DMAR-IR: Failed to copy IR table for dmar1 from previous kernel
[    0.004000] DMAR-IR: IRQ remapping was enabled on dmar0 but we are not in kdump mode
[    0.004000] DMAR-IR: Failed to copy IR table for dmar0 from previous kernel
[    0.004000] DMAR-IR: IRQ remapping was enabled on dmar3 but we are not in kdump mode
[    0.004000] DMAR-IR: Failed to copy IR table for dmar3 from previous kernel

For non-kdump case, we no need to copy IR table from previous kernel
so it's nonthing actually failed. To be less alarming or misleading,
do not print "DMAR-IR: Failed to copy IR table for dmar[0-9] from
previous kernel" messages when booting non-kdump kernel.
