Roland Dreier 7c7a9bccd2 IB/cm: Fix infiniband_cm class kobject ref counting
Commit 9af57b7a ("IB/cm: Add basic performance counters") introduced a
bug in how the reference count for cm_class.subsys.kobj was handled:
the path that released a device did a kobject_put() on that kobject, but
there was no kobject_get() in the path the handles adding a device.  So
the reference count ended up too low, which leads to bad things.  Fix up
and simplify the reference counting to avoid this.

(Actually, I introduced the bug when fixing the patch up to match some
of Greg's kobject changes, but who's counting)
