Administer some love to the osd_req_decode_sense function * Fix a bad bug with osd_req_decode_sense(). If there was no scsi residual, .i.e the request never reached the target, then all the osd_sense_info members where garbage. * Add grossly missing in/out_resid to osd_sense_info and fill them in properly. * Define an osd_err_priority enum which divides the possible errors into 7 categories in ascending severity. Each category is also assigned a Linux return code translation. Analyze the different osd/scsi/block returned errors and set the proper osd_err_priority and Linux return code accordingly. * extra check a few situations so not to get stuck with inconsistent error view. Example an empty residual with an error code, and other places ... Lots of libosd's osd_req_decode_sense clients had this logic in some form or another. Consolidate all these into one place that should actually know about osd returns. Thous translating it to a more abstract error.
