hw/m68k/next-cube: Make next_irq GPIO inputs to NEXT_PC device 

Make the next_irq function be GPIO inputs to the NEXT_PC
device, rather than a freestanding set of qemu_irq lines.

This fixes a minor Coverity issue where it correctly points
out the trivial memory leak of the memory allocated in the
call to qemu_allocate_irqs().

Fixes: CID 1421962
