[ofw] [PATCH] core: add new async events

[Sean Hefty]

Define additional async event types for GID, LID, PKey, and SM
changes.  These are reported by winverbs, and at least appear to
be handled by the HCA drivers.

This avoids converting LID change events seen by the mlx4 driver
into local fatal errors.
