block: sysfs fix mismatched queue_var_{store,show} in 64bit kernel

In blk-sysfs.c, queue_var_store uses unsigned long to store data,
but queue_var_show uses unsigned int to show data.  This causes,

	# echo 70000000000 > /sys/block/<dev>/queue/read_ahead_kb
	# cat /sys/block/<dev>/queue/read_ahead_kb => get wrong value

Fix it by using unsigned long.

While at it, convert queue_rq_affinity_show() such that it uses bool
variable instead of explicit != 0 testing.
