LU-8472 scrub: try to avoid recovery during OI scrub

It is known issue that FID based operation will hit -EINPROGRESS
or -EREMCHG failure if related OI mapping is invalid (most cases
because file-level backup/restore).

On the other hand, the recovery for cross-MDTs modifications will
trigger FID based operation(s) before OI scrub rebuilding related
OI mappings.

So during sanity-scrub tests, the scripts should avoid cross-MDTs
recovery via sync all transactions before file-level backup.

More warning message about the recovery failure if because of bad
OI mappings.

Another fix is about setting LOC_F_NEW flag for the object to be
created via out_create().
