RDMA/device: Add ib_device_get_by_netdev()
Several drivers need to find the ib_device from a given netdev. rxe needs
this at speed in an unsleepable context, so choose to implement the
translation using a RCU safe hash table.
The hash table can have a many to one mapping. This is intended to support
some future case where multiple IB drivers (ie iWarp and RoCE) connect to
the same netdevs. driver_ids will need to be different to support this.
In the process this makes the struct ib_device and ib_port_data RCU safe
by deferring their kfrees.
