Fix crash in struct-with-sig-2.exp with debug-names target board
Checks
Commit Message
When I run the struct-with-sig-2.exp test with the .debug_names-using
target board, I see a gdb crash. This happens because the reader
throws an exception without calling finalize_all_units. This causes
an assertion failure later because the number of CUs and TUs doesn't
match.
The fix is to clear 'all_units' on failure.

I see this is my fault, I added this error and forgot to add the clear,
sorry about that.
Anyway, LGTM.
I've also applied the patch and confirmed that gdb doesn't crash anymore.

I assumed it was my fault from the background reader series :)
I didn't really look though.
