The test to return SUCCESS or FAILURE at the end of nandwrite is done 
only when reading from a file. When reading from the standard input, 
nandwrite always returns success except for some cases at the begining.

This patches aims at fixing that by returning an error when jumping to 
the closeall label.

Regards,
