genirq: Unexport nr_irqs 



Unexport nr_irqs and declare it static now that all code that reads or
modifies nr_irqs has been converted to number_of_interrupts() /
set_number_of_interrupts(). Change the type of 'nr_irqs' from 'int' into
'unsigned int' to match the return type and argument type of the
irq_get_nr_iqs() / irq_set_nr_irqs() functions.
