IB/ipath: Better handling of unexpected GPIO interrupts
The General Purpose I/O pins can be configured to cause interrupts. At the end of the interrupt code dealing with all known causes, a message is output if any bits remain un-handled. Since this is a "can't happen" scenario, it should only be triggered by bugs elsewhere. It is harmless, and potentially beneficial, to limit the damage by masking any such unexpected interrupts. This patch adds disabling of interrupts from any pins that should not have been allowed to interrupt, in addition to emitting a message.
