fix: swapping order of parameters in create_dir_symlink method. (#5465)

Order of parameters in create_dir_symlink method looks wrong. Because
this we get the error "PermissionError: [WinError 5] Denied access:
'.\\deepspeed\\ops\\csrc'" when install deepspeed >= 0.4.0 on Windows
enviroment.

Please check this out @eltonzheng and @jeffra.
