Revert 1.43 - this fix for PHH in blocking mode breaks SSL_accept and

SSL_connect in blocking mode.

While this will probably need a rethink, until we land on a solution
for PHH in blocking mode, the breakage this causes is visible in
real things, and we've only managed to hit the PHH breakage in
a test case.
