[ Upstream commit 0844370f8945086eb9335739d10205dcea8d707b ]
tls_sk_poll is called without locking the socket, and needs to read
strp->msg_ready (via tls_strp_msg_ready). Convert msg_ready to a bool
and use READ_ONCE/WRITE_ONCE where needed. The remaining reads are
only performed when the socket is locked.
Fixes: 121dca784fc0 ("tls: suppress wakeups unless we have a full record")
