RDMA/mlx5: Send events from IB driver about device affiliation state

Browse source 
[ Upstream commit 0d293714ac ]

Send blocking events from IB driver whenever the device is done being
affiliated or if it is removed from an affiliation.

This is useful since now the EN driver can register to those event and
know when a device is affiliated or not.
