Re: comdat_hash memory leaks

I missed another field that needs freeing.  Also, oss-fuzz found a
case with a C_FILE sym using multiple auxents for a long file name
which overflowed the single auxent buffer.  I'm going to fix that
problem in swap_aux_in too, but we may as well avoid it here too,
saving unnecessary work.

	* coffcode.h (comdat_delf): Free comdat_name.
	(fill_comdat_hash): Only look at symbols with one auxent.
