[syslinux] SYSLINUX 3.08-pre1: fix performance regression

[H. Peter Anvin]

I just released SYSLINUX 3.08-pre1.  I believe this should fix the 
performance regression for SYSLINUX/FAT in the 3.0x releases; it seems 
that due to a bug in the logic that computes contiguous I/O transfer 
blocks, the -s option was in effect always enabled.

USB turns out to be a red herring; it affects all boot media.

Please try it out and see if it helps your boot performance.
