smb: move create_durable_reconn to common/smb2pdu.h
The fields in struct create_durable_reconn_req and struct create_durable
are exactly the same, so remove create_durable_reconn_req from server,
and use typedef to define both create_durable_req_t and
create_durable_reconn_t for a single struct.
Rename the following places:
- struct create_durable -> create_durable_req_t
- struct create_durable_reconn_req -> create_durable_reconn_t
The documentation references are:
- SMB2_CREATE_DURABLE_HANDLE_REQUEST in MS-SMB2 2.2.13.2.3
- SMB2_CREATE_DURABLE_HANDLE_RECONNECT in MS-SMB2 2.2.13.2.4
- SMB2_FILEID in MS-SMB2 2.2.14.1
Descriptions of the struct fields:
- __u8 Reserved[16]: DurableRequest field of SMB2_CREATE_DURABLE_HANDLE_REQUEST.
A 16-byte field that MUST be reserved.
- __u64 PersistentFileId: Persistent field of 2.2.14.1 SMB2_FILEID
- __u64 VolatileFileId: Volatile field of 2.2.14.1 SMB2_FILEID
- struct Fid: Data field of SMB2_CREATE_DURABLE_HANDLE_RECONNECT.
An SMB2_FILEID structure, as specified in section 2.2.14.1.
