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.
