Patch to testsuites/libtests/termios01/init.c

This patch to the termios01 test results in failure of the test.

The reason was an RTEMS_TOO_MANY during an rtems_termios_open. Up on some
digging, I saw the the rtems_termios_close does not really delete the tty->osem
since it is still in use.

It was taken just before draining the output buffer, but was not released
before deletion.
The patch (attachment 988)releases the semaphore after the buffer is drained.
