[PATCH v2 3/3] efi_loader: Prevent free of uninitialised pointer

[Andrew Goodbody]

Taking a goto to out_of_resources before receive_lengths is assigned
will result in an attempt to free an unitialised pointer. Instead
initialise receive_lengths to NULL on declaration to prevent this from
occurring.

This issue was found by Smatch.
