direct-io: Remove unused DIO_ASYNC_EXTEND flag

Browse Source 
This flag was added by 6039257378 ("direct-io: add flag to allow aio
writes beyond i_size") to support XFS. However, with the rework of
XFS' DIO's path to use iomap in acdda3aae1 ("xfs: use iomap_dio_rw")
it became redundant. So let's remove it.
