Added write_unit_size field to bdev structure. It describes required number of logical blocks for write operation. For legacy bdevs this value will be equal to logical block size. For bdevs working on top of Open Channel/Zoned Namespace SSDs or RAID 5 volumes write size unit could be greater than logical block size and upper layer should perform write operations with size of multiple of write unit size.
