[ Upstream commit 8dd992fb67f33a0777fb4bee1e22a5ee5530f024 ]
cmd.bad_sector currently gets packed into the sense INFORMATION field for TCM_LOGICAL_BLOCK_{GUARD,APP_TAG,REF_TAG}_CHECK_FAILED errors, which carry an .add_sector_info flag in the sense_detail_table to ensure this.
In preparation for propagating a byte offset on COMPARE AND WRITE TCM_MISCOMPARE_VERIFY error, rename cmd.bad_sector to cmd.sense_info and sense_detail.add_sector_info to sense_detail.add_sense_info so that it better reflects the sense INFORMATION field destination.
