core/smack: downgrade info to debug

BogdanR> I think it's cool it supports SMACK and that it encourages
         them to use a propper mount point for smackfs but I don't
         think it's cool that it's printing on the screen even when
         I parse quiet to the kernel that "SMACK support is not
         enabled ...".
