Use public interfaces to manage the nested rate limit send tag.

Each TLS send tag in mlx5 contains a nested rate limit send tag.
Previously, the driver was calling internal functions to manage the
nested tag.  Calling free methods directly instead of m_snd_tag_rele()
leaked send tag references and references on the ifp.  Changes to use
the ifp methods for the nested tag for other methods are more cosmetic
but do simplify the code.
