[PATCH v2 009/113] efi: payload: image: return actual read_file() error

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

read_file returns NULL on error and sets errno, e.g. to ENOMEM if the
image to be booted exceeds memory available to barebox. Yet, errno was
ignored and EINVAL was returned as error code unconditionally. Fix this
to improve user experience.
