Roman Kagan 666265036f chardev/char-socket: tcp_chr_sync_read: don't clobber errno
After the return from tcp_chr_recv, tcp_chr_sync_read calls into a
function which eventually makes a system call and may clobber errno.

Make a copy of errno right after tcp_chr_recv and restore the errno on
return from tcp_chr_sync_read.
