scsi: core: Rename and move get_scsi_ml_byte()
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.
