small coffgen.c tidy

_bfd_coff_free_cached_info should always call
_bfd_generic_bfd_free_cached_info, even if _bfd_coff_free_symbols
returns an error.  (It won't return an error here, but let's not leave
anyone wondering about _bfd_coff_free_cached_info.)

	* coffgen.c (_bfd_coff_free_cached_info): Ignore return status
	of _bfd_coff_free_symbols.
