ksmbd: Fix refcount leak when invalid session is found on session lookup

Browse source

commit cafb57f7bd upstream.

When a session is found but its state is not SMB2_SESSION_VALID, It
indicates that no valid session was found, but it is missing to decrement
the reference count acquired by the session lookup, which results in
a reference count leak. This patch fixes the issue by explicitly calling
ksmbd_user_session_put to release the reference to the session.
