Title
nvme-tcp: fix UAF when detecting digest errors
Summary
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.
