block: cleanup REQ_SOFTBARRIER usages
Tejun Heo [Thu, 23 Apr 2009 02:05:18 +0000 (11:05 +0900)]
blk_insert_request() doesn't need to worry about REQ_SOFTBARRIER.
Don't set it.  Combined with recent ide updates, REQ_SOFTBARRIER is
now only used in elevator proper and for discard requests.

[ Impact: cleanup ]
