cifs: Silence uninitialized variable warning

This is not really a runtime issue but Smatch complains that:

    fs/cifs/smb2ops.c:1740 smb2_query_symlink()
    error: uninitialized symbol 'resp_buftype'.

The warning is right that it can be uninitialized...  Also "err_buf"
would be NULL at this point and we're not supposed to pass NULLs to
free_rsp_buf() or it might trigger some extra output if we turn on
debugging.
