[LU-3454] open (O_TRUNC) and truncate(0) on a released file must not trig a restore

Duplicate — Wed, 5 Aug 2020 13:32:55 +0000

HSM restore is triggered on data access, to avoid useless restore, it is better to remove released state at open(O_TRUNC) or truncate(0).
For truncate(size != 0) a full restore must be done first (a partial one can be done in a futur patch).
