gas fixup_segment tidy

[Alan Modra]

The return from fixup_segment has been ignored ever since non-BFD gas
support was removed, so..

	* write.c (fixup_segment): Return void.  Delete seg_reloc_count
	related code.
	(TC_ADJUST_RELOC_COUNT): Delete.
	* config/tc-i960.h (TC_ADJUST_RELOC_COUNT): Delete.
