dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING for remapped allocations
We need to return a dma_addr_t even if we don't have a kernel mapping.
Do so by consolidating the phys_to_dma call in a single place and jump
to it from all the branches that return successfully.
Fixes: bfd56cd60521 ("dma-mapping: support highmem in the generic remap allocator")
