aio: fix build when migration is disabled
When "fs/aio: Add support to aio ring pages migration" was applied, it broke the build when CONFIG_MIGRATION was disabled. Wrap the migration code with a test for CONFIG_MIGRATION to fix this and save a few bytes when migration is disabled. Signed-off-by: Benjamin LaHaise <bcrl@kvack.org>
