[PATCH] Fix dmar_ir_support() section mismatch

[Alberto Bertogli]

dmar_ir_support() uses the static dmar_tbl variable, which is annotated as
__initdata. This causes a section mismatch because the function is not
annotated as __init.

Since it is only used by (__init) intr_remapping_supported(), fix the
mismatch by annotating it with __init.

The code was introduced by commit 074835f0, Sep 9 2009.
