[PATCH v1 09/11] media: intel/ipu6: unmap the dummy L2 page table in ipu6_mmu_destroy()

[Valerii Sokolov]

ipu6_mmu_destroy() frees mmu_info->dummy_l2_pt with free_page() instead
of the existing free_dummy_l2_pt() helper, so the streaming DMA mapping
of the dummy L2 page table (mmu_info->dummy_l2_pteval) is never unmapped
when the MMU is torn down.

Use free_dummy_l2_pt().
