char-pty: remove the check for connection on write 

This doesn't help much compared to the 1 second poll PTY
timer. I can't think of a use case where this would help.

However, we can simplify the code around chr_write(): the write lock
is no longer needed for other char-pty callbacks (see following
patch).
