UPSTREAM: net/tls: swap sk_write_space on close

[ Upstream commit 57c722e932cfb82e9820bbaae1b1f7222ea97b52 ]

Now that we swap the original proto and clear the ULP pointer
on close we have to make sure no callback will try to access
the freed state. sk_write_space is not part of sk_prot, remember
to swap it.
