Subject: [PATCH] mount: don't propagate errors from mount_setup_unit() further
 up

If we can't process a specific line in /proc/self/mountinfo we should
log about it (which we do), but this should not affect other lines, nor
further processing of mount units. Let's keep these failures local.

Fixes: #10874

(cherry picked from commit ba0d56f55f2073164799be714b5bd1aad94d059a)

Resolves: #2039327
