Fix hotplug of devices for ib_umad module: when a device goes away,
kill off all MAD agents for open files associated with that device,
and make sure that the device is not touched again after ib_umad
returns from its remove_one function.

Don't build ipoib_mcast_iter_ functions if CONFIG_INFINIBAND_IPOIB_DEBUG
is not enabled -- their only callers will not be built either.
Also move the prototype for ipoib_open() to ipoib.h to fix a sparse warning.

really meant to be displayed in decimal, e.g. 0x000400070190 is
version 4.7.400. Change the format we use from "%x.%x.%x" to
"%d.%d.%d" to match this convention.
