sif: eq: increase cq_eq_max to 46

PSIF supports 48 msi-x interrupts. We associate one msi-x per event
queue (EQ). Further, PSIF need one eq for epsc and one for async
events from the hardware. That leaves 46 for completion notification
events or completion vectors.

This commit also reduces the number of completion notification event
queues to the lesser of the number of cpus present and the default.

Note, this requires fw 1.0.0.1 or newer...
