[U-Boot] [PATCH 1/2] efi_selftest: creating new handle in controller test

[Heinrich Schuchardt]

When the last protocol interface is uninstalled the handle is deleted but
this does not set the value of the handle to NULL.

To create a new handle with OpenProtocolInterface the value of the handle
must be NULL.
