[gdb/symtab] Fix duplicate CUs in create_cus_from_debug_names_list

Browse Source 
When running test-case gdb.dwarf2/clang-debug-names.exp, I run into the
following warning:
...
(gdb) file clang-debug-names^M
Reading symbols from clang-debug-names...^M
warning: Section .debug_aranges in clang-debug-names has duplicate \
  debug_info_offset 0xc7, ignoring .debug_aranges.^M
...

This is caused by a missing return in commit 3ee6bb113a "[gdb/symtab] Fix
incomplete CU list assert in .debug_names".

Fix this by adding the missing return, such that we have instead this warning:
...
(gdb) file clang-debug-names^M
Reading symbols from clang-debug-names...^M
warning: Section .debug_aranges in clang-debug-names \
  entry at offset 0 debug_info_offset 0 does not exists, \
  ignoring .debug_aranges.^M
...
which is a known problem filed as PR25969 - "Ignoring .debug_aranges with
clang .debug_names".

Tested on x86_64-linux.
