Subject: [PATCH] Make sure the mount units pulled by 'RequiresMountsFor=' are
loaded (if they exist)
We should make sure that mount units involved by 'RequiresMountsFor='
directives are really loaded if not required by any others units so
that Requires= dependencies on the mount units are applied and thus
the mount unit dependencies are started.
(cherry-picked from commit c7c89abb9edf9320246482bf4a8e0656199281ae)
Resolves: #1619743
