dma-pool: fix page leak in atomic_pool_expand() cleanup

atomic_pool_expand() frees the allocated pages from the remove_mapping
error path only when CONFIG_DMA_DIRECT_REMAP is enabled.

When CONFIG_DMA_DIRECT_REMAP is disabled, failures after page allocation,
such as gen_pool_add_virt(), jump to remove_mapping and return without
freeing the pages.

Move __free_pages(page, order) out of the CONFIG_DMA_DIRECT_REMAP block so
that cleanup paths always release the allocation.
