fs: fat: fix fat iteration

According to the FAT specification it is valid to have files with an
attribute value of 0x0. This fixes a regression where different U-Boot
versions are showing different amount of files on the same storage
device. With this change U-Boot shows the same number of files and folders
as Linux and Windows.
