Revert 455aa1e08 and c3767ed0eb

    commit c3767ed0eb5d0bb25fe409ae5dec06e3411ff1b6
    qemu-char: (Re-)connect for tcp_chr_write() unconnected writing

Has no hope of working because tcp_chr_connect() does not actually connect.

455aa1e08 just fixes the SEGV with server() but the attempt to connect a client
socket is still completely broken.

This patch reverts both.
