[PATCH v26 10/17] memory: Set DIRTY_MEMORY_MIGRATION when IOMMU is enabled

[Kirti Wankhede]

mr->ram_block is NULL when mr->is_iommu is true, then fr.dirty_log_mask
wasn't set correctly due to which memory listener's log_sync doesn't
get called.
This patch returns log_mask with DIRTY_MEMORY_MIGRATION set when
IOMMU is enabled.
