ext4: Split uninitialized extents for direct I/O
When writing into an unitialized extent via direct I/O, and the direct I/O doesn't exactly cover the unitialized extent, split the extent into uninitialized and initialized extents before submitting the I/O. This avoids needing to deal with an ENOSPC error in the end_io callback that gets used for direct I/O. When the IO is complete, the written extent will be marked as initialized.
