Summary:
- stdin/stdout/stderr are now preallocated in libc and fs_fd
in file_struct are also initialized to -1
- So we need to call fdopen() for stdin again as we did before.
- Also, cn_outstream and cn_errstream are not needed to be set.
- See apps/nshlib/nsh_console.h as well
Impact:
- nsh_usbconsole.c only
Testing:
- Tested with stm32f4discovery:usbnsh

since it is wrong to close the builtin stream and specially note
https://pubs.opengroup.org/onlinepubs/9699919799/functions/fclose.html:
Since after the call to fclose() any use of stream results in
undefined behavior, fclose() should not be used on stdin, stdout,
or stderr except immediately before process termination (see XBD
Process Termination), so as to avoid triggering undefined behavior
in other standard interfaces that rely on these streams. If there
are any atexit() handlers registered by the application, such a
call to fclose() should not occur until the last handler is
finishing. Once fclose() has been used to close stdin, stdout, or
stderr, there is no standard way to reopen any of these streams.
and it is also unnecessary because the stream always get flushed.

1.Avoid the code duplication
2.Call BOARDIOC_FINALINIT onnce and only once
3.Ensure BOARDIOC_FINALINIT get called in all case

1.Remove void cast for function because many place ignore the returned value witout cast
2.Replace void cast for variable with UNUSED macro
