    MINOR: ssl: Remove unused variable "need_out".
    
    The "need_out" variable was used to let the ssl code know we're done
    reading early data, and we should start the handshake.
    Now that the handshake function is responsible for taking care of reading
    early data, all that logic has been removed from ssl_sock_to_buf(), but
    need_out was forgotten, and left. Remove it know.
    This patch was submitted by William Dauchy <w.dauchy@criteo.com>, and should
    fix github issue #434.
    This should be backported to 2.0 and 2.1.
