mpi3mr: Process LOG Data Events in Interrupt Top Half for Early Notification

The driver now processes LOG Data events in the interrupt top
half instead of the bottom half. This allows LOG events to be
handled immediately upon receipt, reducing latency and enabling
early notification to the Library or applications.

This change ensures LOG event handling occurs closer to the
firmware's generation point, improving alignment with event-driven
diagnostic and monitoring mechanisms.
