Re: [U-Boot] fs: fat: don't call disk_write with zero sector num

In the set_cluster() function, it will convert the buffer size to sector numbers. Then call disk_write() to write by sector. For remaining buffer, the size is less than a sector, call disk_write() again to write them in one sector.

But if the total buffer size is less then one sector, the original code will call disk_write() with zero sector number. It is unnecessary. So this patch fix this. Now it will not call disk_write() if total buffer size is less than one sector.

Applied to u-boot/master, thanks!
