hw/intc/i8259: Refactor pic_read_irq() to avoid uninitialized variable
Some compiler versions are smart enough to detect a potentially
uninitialized variable, but are not smart enough to detect that this
cannot happen due to the code flow:
../hw/intc/i8259.c: In function ‘pic_read_irq’:
../hw/intc/i8259.c:203:13: error: ‘irq2’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
203 | irq = irq2 + 8;
| ~~~~^~~~~~~~~~
Restrict irq2 variable use to the inner statement.
