ibmvnic: Introduce hard reset recovery
Introduce a recovery hard reset to handle reset failure as a result of change of device context following a transport event, such as a backing device failover or partition migration. These operations reset the device context to its initial state. If this occurs during a reset, any initialization commands are likely to fail with an invalid state error as backing device firmware requests reinitialization. When this happens, make one more attempt by performing a hard reset, which frees any resources currently allocated and performs device initialization. If a transport event occurs during a device reset, a flag is set which will trigger a new hard reset following the completionof the current reset event.
