Namjae Jeon de428966b4 ksmbd: fix racy issue from smb2 close and logoff with multichannel
[ Upstream commit abcc506a9a ]

When smb client send concurrent smb2 close and logoff request
with multichannel connection, It can cause racy issue. logoff request
free tcon and can cause UAF issues in smb2 close. When receiving logoff
request with multichannel, ksmbd should wait until all remaning requests
complete as well as ones in the current connection, and then make
session expired.
