A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

nvme-tcp: fix UAF when detecting digest errors

We should also bail from the io_work loop when we set rd_enabled to true, so we don't attempt to read data from the socket when the TCP stream is already out-of-sync or corrupted.
