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.
