  1. [patch] mlxsw: i2c: Prevent transaction execution for special chip 

    states

Do not run transaction in cases chip is in reset or in-filed update states.

This patch fixes an issue encountered during SONiC warm-reboot: during
ISSU start the kernel reports that CPU stall is detected:

```
INFO: rcu_sched detected stalls on CPUs/tasks
```

This patch won't be upstreamed due to the upstream driver not supporting
ISSU.
