fs readdir: check for NULL pointer again 

This got lost in:

commit 6188685091

    Make errno a positive value

    Normally errno contains a positive error value. A certain unnamed developer
    mixed this up while implementing U-Boot-v2. Also, normally errno is never
    set to zero by any library function.
    This patch fixes this.
