ksmbd: fix race condition between destroy_previous_session() and smb2 operations()
If there is ->PreviousSessionId field in the session setup request,
The session of the previous connection should be destroyed.
During this, if the smb2 operation requests in the previous session are
being processed, a racy issue could happen with ksmbd_destroy_file_table().
This patch sets conn->status to KSMBD_SESS_NEED_RECONNECT to block
incoming operations and waits until on-going operations are complete
(i.e. idle) before desctorying the previous session.
