Subject: [PATCH] IB/ipath: use unsigned long for irqflags

PS: Using a bit more context once the patch is applied, it's easier to spot
where the flags are used.

The semantic patch I used was this:

@@
expression lock;
identifier flags;
expression subclass;
@@

- unsigned int flags;
+ unsigned long flags;

...
