[PULL 2/5] hw/ide/sii3112: Use qdev gpio rather than qemu_allocate_irqs()

[John Snow]

From: Peter Maydell <address@hidden>

Coverity points out (CID 1421984) that we are leaking the
memory returned by qemu_allocate_irqs(). We can avoid this
leak by switching to using qdev_init_gpio_in(); the base
class finalize will free the irqs that this allocates under
the hood.
