IB/ipath: Use unsigned long for irq flags

A few functions in the ipath driver incorrectly use unsigned int to
hold irq flags for spin_lock_irqsave().

This patch was generated using the Coccinelle framework with the
following semantic patch:

The semantic patch I used was this:

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

- unsigned int flags;
+ unsigned long flags;
