iommu/amd: Remove redundant domain flush from attach_device()

Browse source

Domain flush was introduced in attach_device() path to handle kdump
scenario. Later init code was enhanced to handle kdump scenario where
it also takes care of flushing everything including TLB
(see early_enable_iommus()).

Hence remove redundant flush from attach_device() function.
