branchcache: stay silent if failing to read cache files
The warning has in some cases incorrectly attributed unrelated problems to rbc.
Instead, just do like the branch head cache does and stay quiet when reading
fails. The cache will be missing the first time a repo is used. It is a normal
situation and there is no reason to make a note of that.
