Fix read past end of struct in ncsw glue code.

The logic in XX_IsPortalIntr() was reading past the end of XX_PInfo.
This was causing it to erroneously return 1 instead of 0 in some
circumstances, causing a panic on the AmigaOne X5000 due to mixing
exclusive and nonexclusive interrupts on the same interrupt line.

Since this code is only called a couple of times during startup, use
a simple double loop instead of the complex read-ahead single loop.

This also fixes a bug where it would never check cpu=0 on type=1.
