efi: Fix error handling in add_sysfs_runtime_map_entry()
I spotted two (difficult to hit) bugs while reviewing this.
1) There is a double free bug because we unregister "map_kset" in
add_sysfs_runtime_map_entry() and also efi_runtime_map_init().
2) If we fail to allocate "entry" then we should return
ERR_PTR(-ENOMEM) instead of NULL.
