Subject: [PATCH][i3c-next] i3c: fix incorrect update to max_read_ds

From: Colin Ian King <colin.king@...onical.com>

Currently max_read_ds is being updated twice, which is incorrect.
The second assignment should be to max_write_ds instead. Fix this.

Detected by CoverityScan, CID#1475379 ("Unused value")
