btrfs restore prints "offset is " messages, even without verbose option

[keestux]

When I run btrfs restore without verbose option it prints lines like these:

$ sudo btrfs restore --root 4339 --snapshots --metadata --symlinks --ignore-errors /dev/sdc2 /tmp/my-restored-subvol
offset is 4096
offset is 8192
offset is 36864
offset is 4096
offset is 53248
offset is 4096

There is no documentation what these messages mean. Is it an error? Is it a message that should only be given with verbose option?

It is from line 394 in cmds/restore.c

	pr_verbose(offset ? 1 : 0, "offset is %llu\n", offset);

Perhaps the 1 should probably have been LOG_INFO. No?

Besides, it would be useful for the user to know what this message means.
