fmt_ti: fix lsb/msb mix-up in ti_hr_from_canon()

I noticed that ti-hr format doesn't pass an encode-decode-playback test,
and discussion with tnt resulted in the following conclusion:

19:29 <@tnt> looking at fr and efr, it's always msb_xxx
19:30 <@tnt> and if I ever used it, then most likely it was for decoding
             meaning ti_hr_to_canon would have been used and not the
             other way around.
