[PATCH] efi: payload: do not check for heap addresses in efi_load_image

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

We used to request memory from EFI only if read_file fails, but now that
read_file has been removed from efi_read_file, only EFI memory is used.

The check in efi_free_file for heap addresses thus serves no purpose any
longer and can be dropped.
