This is when we create an new inode, so neither i_acl nor
i_default_acl should be ACL_NOT_CACHED when this function succeeds. So
either we should make sure that i_acl and i_default_acl are already
not set to ACL_NOT_CACHED anymore when entering this function, or
cache_no_acl should be called unconditionally before setting the
actual ACLs.

Thanks,
Andreas
