libata and bogus LBA48 drives

A colleague noticed recent versions of Ubuntu no longer detect his 80 GB
ST380020ACE drive. This drive is special in that it advertises LBA48 support,
but has the lba_capacity_2 field set to zero (cfr.
http://lkml.org/lkml/2004/3/30/163).

Upon closer look, libata indeed doesn't seem to handle this case yet.
Below is an (untested) fix.
