RDMA/device: Consolidate ib_device per_port data into one place
There is no reason to have three allocations of per-port data. Combine them together and make the lifetime for all the per-port data match the struct ib_device. Following patches will require more port-specific data, now there is a good place to put it. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
