aio: remove an outdated BUG_ON and comment in aio_complete
These days we don't treat sync iocbs special in the aio completion code as they never use it. Remove the old comment and BUG_ON given that the current definition of is_sync_kiocb makes it impossible to hit. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com>
