Btrfs-progs: pass properly formated key to read_fs_root

Browse Source 
We have a BUG_ON() in read_fs_root that expects key->offset == (u64)-1.  Restore
will just pass in the location it reads out of the inode if it has a subvol
reference and pass that in, which doesn't have offset == (u64)-1, so it causes
restore blow up.  This was reported in bugzilla and this patch fixed the
problem.  Thanks,
