[Intel-wired-lan] [PATCH net 5/6] xsk: move xsk_tx_metadata_request() to xdp_sock_drv.h

xsk_tx_metadata_request() must validate metadata with
xsk_buff_valid_tx_metadata(), which is defined in xdp_sock_drv.h. Move the
helper there before adding that dependency. All callers already include
the destination header, so this has no functional effect.

Fixes: ca4419f15abd ("xsk: Add launch time hardware offload support to XDP Tx metadata")
