net/ulp: remove SOCK_SUPPORT_ZC from tls sockets
Remove SOCK_SUPPORT_ZC when we're setting ulp as it might not support
msghdr::ubuf_info, e.g. like TLS replacing ->sk_prot with a new set of
handlers.
Cc: <stable@vger.kernel.org> # 6.0
Reported-by: Jakub Kicinski <kuba@kernel.org>
Fixes: e993ffe3da4bc ("net: flag sockets supporting msghdr originated zerocopy")
