 Remove unnecessary loadInterface for TH quoted name.

 Summary:
 The load was introduced a32d3e4da0aceb624c958f02cad7327e17ac94db
 to fix a bug where deprecations assumed that the name in question
 had already had their interface loaded.  The new deprecation
 code no longer makes this assumption and just loads the interface,
 so this eager load is not necessary.

 Verified that TH_reifyType2 continues to work.
