dwarf-reader: fix recursion in expr_result::operator&

operator& was implemented in terms of itself, leading to infinite
recursion. Fix that by implementing it in terms of &='ing the const
value. That is consistent with all other ?= operators.

 * src/abg-dwarf-reader.cc: fix expr_result::operator&
