Sayali Lokhande 95a77b5a1a Revert "block: fix the DISCARD request merge" ...

This reverts commit 10807b3746.
This is needed to fix regression observed in reboot path,
where discard requests are merged and for some reason merged
request is not properly freed or cleaned up resulting in panic
in __blk_put_request().
