Ed Swierk 1c64fdbc81 char: drop data written to a disconnected pty 
When a serial port writes data to a pty that's disconnected, drop the
data and return the length dropped. This avoids triggering pointless
retries in callers like the 16550A serial_xmit(), and causes
qemu_chr_fe_write() to write all data to the log file, rather than
logging only while a pty client like virsh console happens to be
connected.
