John Beard acb005f044 Netclass: allow multiple assignments with the same pattern
This isn't really a problem, and overwriting the entry allows
for silent data loss by making a new assignment with the
same pattern as an existing one.

The resolve netclasses are de-duplicated later, so it's even
OK if the whole assignment is duplicated (in theory), but
continue to clean these up.
