SCSI has two different getters:
- get_XXX_byte() (in scsi_cmnd.h) which takes a struct scsi_cmnd *, and
- XXX_byte() (in scsi.h) which takes a scmd->result.
The proper name for get_scsi_ml_byte() should thus be without the get_
prefix, as it takes a scmd->result. Rename the function to rectify this.
(This change was suggested by Mike Christie.)

Additionally, move get_scsi_ml_byte() to scsi_priv.h since both scsi_lib.c
and scsi_error.c will need to use this helper in a follow-up patch.
