iwlwifi: fix ICT irq table endianness
The ICT IRQ table is a set of __le32 values, not u32 values,
so when reading it we need to take into account that it has
to be converted to CPU endianness. This was causing a lot of
trouble on my powerpc box where various things would simply
not work for no apparent reason with 5xxx cards, but worked
with 4965 -- which doesn't use the ICT table.
