[PATCH v4 18/24] smb: move create_durable_rsp_v2 to common/smb2pdu.h

chenxiaosong.chenxiaosong
2025-10-27T07:23:49Z

From: ChenXiaoSong <chenxiaosong@kylinos.cn>

Replace some fields in "struct create_durable_v2_rsp" with "struct
durable_context_v2_rsp", rename 2 places:

- durable_reconnect_context_v2_rsp -> durable_context_v2_rsp
- create_durable_v2_rsp -> create_durable_rsp_v2

Then move them to common header file.
