6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lucas Stach <l.stach@xxxxxxxxxxxxxx>
[ Upstream commit 1d9cabe2817edd215779dc9c2fe5e7ab9aac0704 ]
Use the proper size when setting up the bio_vec, as otherwise only
zero-length UDP packets will be sent.
Fixes: baabf59c2414 ("SUNRPC: Convert svc_udp_sendto() to use the per-socket bio_vec array")
