bde 562a666ce0 Test the correct nonblocking flag in ttylclose(). IO_NDELAY is only valid 
in read() and write().  FNONBLOCK is valid in ioctl() and close().

The bug caused hung ptys when a process talked to itself using nonblocking
i/o and exited while the slave pty had output to flush.  ttywait() was
called and hung.  Signals didn't work because the process was exiting.
`comcontrol /dev/ttyp0 drainwait 1' worked to terminate the wait.  This
shows that comcontrol is not limited to hardware control.  It has no i386
or driver dependencies and doesn't belong in src/sbin/i386.
