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;
