uefi: Fix lifetimes in device_path TryFrom<&[u8]> impls

The missing lifetime means that the &[u8] buffer could be freed while the
&DevicePath still exists, which is UB.

+## Changed
+- **Breaking:**: Fixed a bug in the impls of `TryFrom<&[u8]>` for
+  `&DevicePathHeader`, `&DevicePathNode` and `&DevicePath` that could lead to
+  memory unsafety. See <https://github.com/rust-osdev/uefi-rs/issues/1281>.
