Possible bug in 'open.c'

I think I've found minor bug in the open() routine (rtems-ss-20030128).
rc = ftruncate( iop - rtems_libio_iops, 0 );
if the call to ftruncate() somehow fails, the open() will return -1 but
will not close actual file that has been opened by
rc = (*iop->handlers->open_h)( iop, pathname, flags, mode );
As open() returns -1, the caller also will not try to call close() thus
leaving the file open.
ftruncate() can fail, e.g., if particular handler doesn't support the
file truncate feature.
