[PATCH 5.7 111/112] dm zoned: assign max_io_len correctly

[Greg Kroah-Hartman]

From: Hou Tao <hout...@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")
