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.

Add a Linux driver module that registers as a SCSI ULD and probes
for OSD type SCSI devices.
When an OSD-type SCSI device is found a character device is created
in the form of /dev/osdX - where X goes from 0 up to hard coded 64.
The Major character device number used is 260.
