iommu/io-pgtable: fix __arm_lpae_free_pgtable leak
When unmapping 2MB mappings, which are 2MB aligned, the smmu driver
is leaking the 3rd level page tables.
Fix this leak by updating __arm_lpae_free_pgtable so that it no
longer leaks leaf table entries.
To reproduce this leak simply map and unmap a non-block 2MB mapping
which is 2MB aligned.
