It is now possible to submit a write request with a sequence of accel operations that need to be executed before actually writing the data. Such requests will be directly passed to a bdev module (so that it can append subsequent operations to an accel sequence) if that bdev supports accel sequences and the request doesn't need to be split. If either of these conditions are not met, bdev layer will execute all the accumulated accel operations before passing the request to a bdev module. The reason for not submitting split IOs with an accel sequence is that we would need to split that accel sequence too. Currently, there's no such functionality in accel, so we treat this case in the same way as if the underlying bdev module didn't support accel sequences (it's executed before bdev_io is split).
