blktrace: Trace remapped requests correctly

[ Upstream commit 22c80aac882f712897b88b7ea8f5a74ea19019df ]

Trace the remapped operation and its flags instead of only the data
direction of remapped operations. This issue was detected by analyzing
the warnings reported by sparse related to the new blk_opf_t type.
