From: Darren Kenny <darren.ke...@oracle.com>
The static code analysis tool, Parfait, reported that the valid of
file->data was left referencing memory that was freed by the call to
grub_free(data) where data was initialized from file->data.
To ensure that there is no unintentional access to this memory
referenced by file->data we should set the pointer to NULL.
