sata_vsc: use default cache line size if non-zero

This modifies drivers/ata/sata_vsc.c to only set the cache line size
to 0x80 if the default value is zero. Apparently zero isn't allowed
due to a bug in the chip, but I've found performance is much better
with the (non-zero) default instead of 0x80.

[note1: "default" means BIOS-programmed value, in this context -jgarzik]

[note2: superfluous braces were removed from the patch -jg]
