iommu: Properly export iommu_group_get_for_dev()
commit ae74c19faa7d7996e857e13165bd40fc4a285e0d upstream.
In commit a7ba5c3d008d ("drivers/iommu: Export core IOMMU API symbols to
permit modular drivers") a bunch of iommu symbols were exported, all
with _GPL markings except iommu_group_get_for_dev(). That export should
also be _GPL like the others.
Fixes: a7ba5c3d008d ("drivers/iommu: Export core IOMMU API symbols to permit modular drivers")
