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.
Trivial conflict in src/core/mount.c, function mount_load_proc_self_mountinfo,
due to local commit ca634baa10e. Also, due to the same commit, int k
is no longer used and is thus removed.

Resolves: #2036853
