Implementation of the osd_req_decode_sense() API. Can be called by
library users to decode what failed in command executions.
Add SCSI_OSD_DPRINT_SENSE Kconfig variable. Possible values are:
0 - Do not print any errors to messages file <KERN_ERR>
1 - (Default) Print only decoded errors that are not recoverable.
Recoverable errors are those that the target has complied with
the request but with a warning. For example read passed end of
object will return zeros after the last valid byte.
2- Print all errors.
