From: Hou Tao <houtao1@huawei.com>
commit 7b2377486767503d47265e4d487a63c651f6b55d upstream.
The unit of max_io_len is sector instead of byte (spotted through
code review), so fix it.
Fixes: 3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")

5.7, 5.4, 4.19 and 4.14.
Got the automated email that the patch was not applying so I sent this corrected
version. I sent you a separate note about this.
Thanks !

Yes, but given the huge email flow, you need to be specific as your
response there was seen about an hour after this email due to them not
being threaded/attached/whatever :)
