[PATCH] Some small cleanups in add_symbol_overload_list_qualified

[Tom Tromey]

This applies some more cleanups to add_symbol_overload_list_qualified,
consolidating calls to get_selected_block.

It also movesthe symtab expansion call after the code that walks up
from the selected block, merging two loops.
