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]
