Just compile tested.

It's a cleanup suggested by Andrew Lunn [1][2]. His suggestion might 
have been for SMC_PUSH_DATA() and SMC_PULL_DATA() only; or to add 
another macro param for ioaddr if lp->base and ioaddr are different (as 
in smc_probe()).

Yes, it does break smc_probe(). I'll fix it and submit a v2.
