Bart Van Assche b4439abfd7 blktrace: Trace remapped requests correctly
[ Upstream commit 22c80aac88 ]

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.
