Subject: [PATCH bpf] xdp: handle frame_sz in xdp_convert_zc_to_xdp_frame()

In commit 34cc0b338a61 we only handled the frame_sz in convert_to_xdp_frame().
This patch will also handle frame_sz in xdp_convert_zc_to_xdp_frame().

Fixes: 34cc0b338a61 ("xdp: Xdp_frame add member frame_sz and handle in convert_to_xdp_frame")
