[U-Boot] [PATCH v3 7/8] efi_loader: Treat the result of efi_add_memory_map as efi_status_t

[Bryan O'Donoghue]

The return type of efi_add_memory_map() has been updated to return
efi_status_t as a result we should check the return of efi_add_memory_map()
against EFI_SUCCESS as opposed to the original input addr parameter.

This change will also remove this error message on raspberrypi 3 boot: "FDT
memrsv map 0: Failed to add to map".

Fixes: 416e07e2cfcf ("efi: Drop error return in efi_carve_out_dt_rsv()")
