Data corruption when using multiple devices with NVMEoF TCP

[Hao Wang]

Okay, tried both v5.10 and latest 58cf05f597b0.

And same behavior
 - data corruption on the initiator side when creating a raid-0 volume
using 2 nvme-tcp devices;
 - no data corruption either on local target side, or on initiator
side but only using 1 nvme-tcp devoce.

A difference I can see on the max_sectors_kb is that, now on the
target side, /sys/block/nvme*n1/queue/max_sectors_kb also becomes
1280.
