ATA error recovery wants to divert all resets to the eh thread and wait for completion, these handlers may be invoked from a non-blocking ioctl. The other path they are called from is libsas-eh, and if we escalate past I_T_nexus reset we have larger problems i.e. tear down all in-flight commands in the domain potentially without notification to the lldd if it has chosen not to implement ->lldd_clear_nexus_port() / ->lldd_clear_nexus_ha().
