[PATCH 2/6] smb/server: fix return value of smb2_notify()

[chenxiaosong.chenxiaosong@linux.dev]

From: ChenXiaoSong <chenxiaosong@kylinos.cn>

smb2_notify() should return error code when an error occurs,
__process_request() will print the error messages.

I may implement the SMB2 CHANGE_NOTIFY response (see MS-SMB2 2.2.36)
in the future.
