ksmbd: disconnect on SMB3 decryption failure
MS-SMB2 requires the server to disconnect a connection when an
encrypted transform cannot be associated with a session or fails
authenticated decryption. This includes an encrypted request that
still carries a SessionId invalidated through PreviousSessionId.
Move the connection to EXITING and shut down its transport when
decrypt_req() fails. Add the missing TCP shutdown callback so a receive
blocked in kernel_recvmsg() is released; SMB Direct already provides
the corresponding callback.
Plaintext requests using an invalidated SessionId do not take this
path and continue to receive STATUS_USER_SESSION_DELETED.
Fixes: e2f34481b24d ("cifsd: add server-side procedures for SMB3")
