Revert: linespec.c (iterate_name_matcher): Fix arguments to symbol_name_cmp.

This patch causes regressions in ada's operator_bp.exp test.
That's because it uses wild_match which expects arguments in
the original order.

There is still a bug here.  It's hard to see because either minsyms
save the day, or the needed symtab gets expanded before linespecs
need it because of the call to cp_canonicalize_string_no_typedefs
in linespec.c:find_linespec_symbols.
But if you disable both of those things, then the bug is visible.

bash$ ./gdb -D ./data-directory testsuite/gdb.cp/anon-ns
(gdb) b doit(void)
Function "doit(void)" not defined.
