Btrfs: cache no acl on new inodes
When running compilebench I noticed we were spending some time looking up
acls on new inodes, which shouldn't be happening since there were no acls.
This is because when we init acls on the inode after creating them we don't
cache the fact there are no acls if there aren't any. Doing this adds a
little bit of a bump to my compilebench runs. Thanks,
