[PATCH] RDMA: Fix netdev tracker in ib_device_set_netdev

[David Ahern <dsahern@kernel.org>]

If a netdev has already been assigned, ib_device_set_netdev needs to release
the reference on the older but it is mistakenly being called for the new
netdev. Fix it and in the process use netdev_put to be symmetrical with
the netdev_hold.

Fixes: 09f530f0c6d6 ("RDMA: Add netdevice_tracker to ib_device_set_netdev()")
