LU-9120 lnet: handle fatal device error

LU-9120 lnet: handle fatal device error

The o2iblnd can receive device status on the QP event handler.
There are three in specific that are being handled in this patch:
IB_EVENT_DEVICE_FATAL
IB_EVENT_PORT_ERR
IB_EVENT_PORT_ACTIVE
For DEVICE_FATAL and PORT_ERR the NI associated with the QP is set
in fatal error mode. This NI will no longer be selected when sending
messages. When PORT_ACTIVE is received the NI associated with the QP
has the fatal error cleared and future messages can use that NI.
