Fix a possible memory leak in do_othername
Since the gen->type will not be set in a2i_GENERAL_NAME
the gen->d.otherName will not be automatically
cleaned up by GENERAL_NAME_free.
Also fixed a similar leak in a2i_GENERAL_NAME,
where ASN1_STRING_set may fail but gen->d.ia5
will not be automatically cleaned up.
