habanalabs: no consecutive err when user context is enabled 



Consecutive error protects a device reset loop from being triggered
due to h/w issues and enters the device into an unavailable state.
When user may cause the error, an unavailable state
will prevent the user from running its workloads.

The commit prevents entering consecutive state when a user context
is enabled.
