io_uring/net: initialize mshot_len for send
Commit:
6a8afb9fff64 ("io_uring/net: allow multishot receive per-invocation cap")
changed how io_mshot_prep_retry() set sr->len, and added the same
initialization in io_mshot_prep_retry(). But it neglected to touch the
send path, which may also uses the mshot retry path. Ensure that
sr->mshot_len always gets initialized correctly.
Fixes: 6a8afb9fff64 ("io_uring/net: allow multishot receive per-invocation cap")
