For a zone append write, the device decides the location the data is written to. Therefore we cannot ensure that two bios are written consecutively on the device. In order to ensure that a ordered extent maps to a contiguous region on disk, we need to maintain a "one bio == one ordered extent" rule. This commit implements the splitting of an ordered extent and extent map on bio submission to adhere to the rule.
