[Intel-wired-lan] [PATCH net-next 1/3] xsk: align TX metadata layout across ABIs

Add explicit padding before launch_time so xsk_tx_metadata has the same
layout on 32-bit and 64-bit systems. This intentionally replaces the
incompatible 32-bit launch-time layout while the interface is still new.
Fixes: ca4419f15abd ("xsk: Add launch time hardware offload support to XDP Tx metadata")
