irq: Fix circular headers dependency

asm-generic/hardirq.h needs asm/irq.h which might include
linux/interrupt.h as in the sparc 32 case. At this point
we need irq_cpustat generic definitions, but those are
included later in asm-generic/hardirq.h.

Then delay a bit the inclusion of irq.h from
asm-generic/hardirq.h, it doesn't need to be included early.

This fixes:

 include/linux/interrupt.h: In function '__raise_softirq_irqoff':
 include/linux/interrupt.h:414: error: implicit declaration of function 'local_softirq_pending'
 include/linux/interrupt.h:414: error: lvalue required as left operand of assignment
