dpaa2-mac: fix the remove path for non-MAC interfaces



Check if the interface is indeed connected to a MAC before trying to
close the DPMAC object representing it. Without this check we end up
working with a NULL pointer.

Fixes: d87e6063 ("dpaa2-mac: export MAC counters even when in TYPE_FIXED")
