[PATCH 6.18 032/686] smb: align durable reconnect v2 context to 8 byte boundary

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bharath SM <bharathsm@microsoft.com>

[ Upstream commit 05f5e355cf783b30bd6eb3dec17ed1a8b3cfa95c ]

Add a 4-byte Pad to create_durable_handle_reconnect_v2 so the DH2C
create context is 8 byte aligned.
This avoids malformed CREATE contexts on reconnect.
Recent change removed this Padding, adding it back.

Fixes: 81a45de432c6 ("smb: move create_durable_handle_reconnect_v2 to common/smb2pdu.h")
