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.
