bug: btrfs-progs scrub -R flag doesn't show per device stats

[Chris Murphy]

btrfs-progs v4.17.1

man btrfs-scrub:

           -R
               print raw statistics per-device instead of a summary


However, on a two device Btrfs volume, -R does not show per device
statistics. See screenshot:

Additionally, the description of -d and -R doesn't help me distinquish
between the two. -R says "instead of a summary" so that suggests -d
will summarize but isn't explicitly stated.

The description of '-R' is incorrect, it shoudle be 'raw print mode, 
print full data instead of summary'.
The option '-d' do print separate statistics for each device indded,
not the '-R'.

A patch has been sent(forgot to CC you).
