Paul Sokolovsky 0719c936fb extmod/modussl_axtls: socket_read: Handle EAGAIN. 
If SSL_EAGAIN is returned (which is a feature of MicroPython's axTLS fork),
return EAGAIN.

Original axTLS returns SSL_OK both when there's no data to return to user
yet and when the underlying stream returns EAGAIN. That's not distinctive
enough, for example, original module code works well for blocking stream,
but will infinite-loop for non-blocking socket with EAGAIN. But if we fix
non-blocking case, blocking calls to .read() will return few None's initially
(while axTLS progresses thru handshake).

Using SSL_EAGAIN allows to fix non-blocking case without regressing the
blocking one.

Note that this only handles case of non-blocking reads of application data.
Initial handshake and writes still don't support non-blocking mode and must
be done in the blocking way.
