tcp: annotate tp->write_seq lockless reads
[ Upstream commit 0f31746452e6793ad6271337438af8f4defb8940 ]
There are few places where we fetch tp->write_seq while
this field can change from IRQ or other cpu.
We need to add READ_ONCE() annotations, and also make
sure write sides use corresponding WRITE_ONCE() to avoid
store-tearing.
