[SRU][F:linux-bluefield][PATCH 14/21] xdp: Handle frame_sz in xdp_convert_zc_to_xdp_frame()

[Bodong Wang]

From: Hangbin Liu <liuhangbin at gmail.com>

BugLink: https://bugs.launchpad.net/bugs/1934499

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")
