Doc: Don't be too strict on backport request for unsupported versions.

Some users may still be using unsupported releases or branches and
may require some bug fixes.  It is highly recommended to upgrade to
the supported versions.  But sometimes a fix maybe requested by the
users.  Update the documentation to allow such requests if its feasible
to backport such fixes.
