Remove a stray else. It isn't needed (due to the return at the end of

the if statement it pairs with). While not an error today, a careless
edit in the future could cause problems (though given the nature of
this specific code, the problems quite likely would be some variation
of "most direct access SCSI storage devices won't attach," which is
unlikely to go unnoticed).
