kernel: 6.12-6.18: move ksmbd signing fix to backports

The multi-iov signing fix has moved from the SMB code-review tree to
ksmbd-for-next.

Move both patches from pending to backport, number them 502 so the v7.1
session teardown fix is applied first, and refresh them for the new
ordering.

Match the continuation-line indentation in the upstream commit.
