Jason Baron 1b7dbabf02 tcp: correct memory barrier usage in tcp_check_space() ...

[ Upstream commit 56d806222a ]

sock_reset_flag() maps to __clear_bit() not the atomic version clear_bit().
Thus, we need smp_mb(), smp_mb__after_atomic() is not sufficient.

Fixes: 3c7151275c ("tcp: add memory barriers to write space paths")
