11314 Provide psm_get_ipivect even on single CPU systems

This has been in OmniOS for a while to support running under hyper-v on a single CPU. It has been tested on standalone hardware, under hyper-v on windows and in Microsoft Azure.

The hyper-v vmbus driver uses this function to get an interrupt vector, and it is currently not available on a single-CPU system.

I don't believe there is anything else it could use in the context but I'd be happy to be corrected:
