Yunfei Wang e12f983c4a iommu/io-pgtable-arm-v7s: Add error handle for page table allocation failure 
commit a556cfe4cabc6d79cbb7733f118bbb420b376fe6 upstream.

In __arm_v7s_alloc_table function:
iommu call kmem_cache_alloc to allocate page table, this function
allocate memory may fail, when kmem_cache_alloc fails to allocate
table, call virt_to_phys will be abnomal and return unexpected phys
and goto out_free, then call kmem_cache_free to release table will
trigger KE, __get_free_pages and free_pages have similar problem,
so add error handle for page table allocation failure.
