ext4: remove EXT4_STATE_DIOREAD_LOCK flag
Commit 16c54688592c ("ext4: Allow parallel DIO reads") reworked the way locking happens around parallel dio reads. This resulted in obviating the need for EXT4_STATE_DIOREAD_LOCK flag and accompanying logic. Currently this amounts to dead code so let's remove it.
