net: remove SOCK_SUPPORT_ZC from sockmap
sockmap replaces ->sk_prot with its own callbacks, we should remove SOCK_SUPPORT_ZC as the new proto doesn't support msghdr::ubuf_info. Cc: <stable@vger.kernel.org> # 6.0 Reported-by: Jakub Kicinski <kuba@kernel.org> Fixes: e993ffe3da4bc ("net: flag sockets supporting msghdr originated zerocopy") Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
