Pavel Begunkov 2829a267fc net: fix uninitialised msghdr->sg_from_iter 
Because of how struct msghdr is usually initialised some fields and
sg_from_iter in particular might be left out not initialised, so we
can't safely use it in __zerocopy_sg_from_iter().

For now use the callback only when there is ->msg_ubuf set relying on
the fact that they're used together and we properly zero ->msg_ubuf.

Fixes: ebe73a284f4de8 ("net: Allow custom iter handler in msghdr")
