arm: dma-mapping: Fix mapping size value
68efd7d2fb("arm: dma-mapping: remove order parameter from arm_iommu_create_mapping()") is causing kernel panic because it wrongly sets the value of mapping->size: Unable to handle kernel NULL pointer dereference at virtual address 000000a0 pgd = e7a84000 [000000a0] *pgd=00000000 ... PC is at bitmap_clear+0x48/0xd0 LR is at __iommu_remove_mapping+0x130/0x164 Fix it by correcting mapping->size value.
