[U-Boot] fatls shows duplicated entries with long and short names

[Hector Palacios]

Dear Marek,

I noticed that 'fatls' displays duplicated filenames (short and long) for every file 
in the media:

# fatls mmc 0
   2083460   uimage-myplatform
   2083460   uimage~1
      1520   rootfs-dummy.jffs2
      1520   rootfs~1.jff
   3294952   uimage
   3294952   uimage

The guilty commit is ff04f6d1224d8952b566b8671222151495883073 by you, who moved the 
chksum calculation out of an if() and now the code never enters this:

#ifdef CONFIG_SUPPORT_VFAT
			else if (dols == LS_ROOT && csum == prevcksum) {
				prevcksum = 0xffff;
				dentptr++;
				continue;
			}
#endif

Could you please check?

Best regards,
