qcacmn: Fix data type for ic_irqnum
ic_irqnum saves the irq number given by platform,
existing max irq which can be saved per ce is 255,
if platform return irq greater than 255, value is
misinterpreted with that saved in a byte, this will
eventually have problem when host driver suspends/stop,
during which freeing irq will fail.
But in scenarios such as IPI mechanisms such as whunt,
since free irq fails, it would still assume irq is enabled
and call registered handlers, which will lead to
null pointer access.
Inorder to fix this changed data type to uint16_t.
