If a firmware fault occurs while scanning the devices during IOC
initialization then the driver issues the hard reset operation to recover
the IOC. However, the driver is not issuing a Port enable request
message as part of hard reset operation during IOC initialization.  Due to
this, the driver will not receive get any device discovery-related events
and hence devices will not be accessible.

Teach the driver to gracefully handle firmware faults while scanning for
target devices during IOC initialization. Make the driver issue a port
enable request message as part of hard reset operation. This permits
receiving device discovery-related events from the firmware after the hard
reset operation completes.
