George McCollister e0c755a45f net: dsa: don't assign an error value to tag_ops 
Use a temporary variable to hold the return value from
dsa_tag_driver_get() instead of assigning it to dst->tag_ops. Leaving
an error value in dst->tag_ops can result in deferencing an invalid
pointer when a deferred switch configuration happens later.

Fixes: 357f203bb3 ("net: dsa: keep a copy of the tagging protocol in the DSA switch tree")
