Fix bug where we'd try symbolize a second time with the same arguments.

Summary

Fix bug where we'd try symbolize a second time with the same arguments even though symbolization failed the first time.

This looks like a long standing typo given that the guard for trying
symbolization again is to only try it if symbolization failed using
binary and original_binary != binary.

       binary = self.binary_name_filter(binary)
