of_phy_find_device() increments the phy struct device refcount, which
we need to properly balance.  Add code to network drivers using this
function to ensure that the struct device refcount is correctly
balanced.

For xgene, looking back in the history, we should be able to use
of_phy_connect() with a zero flags argument for the DT case as this is
how the driver used to operate prior to de7b5b3d ("net: eth: xgene:
change APM X-Gene SoC platform ethernet to support ACPI").

This leaves the Cavium Thunder BGX unfixed; fixing this driver is a
complicated task, one which the maintainers need to be involved with.

When the driver attaches to a device that has a phy handle the probe
routine returns with a reference to that node. This reference is
correctly dropped in the error path and the remove function. In the
fixed phy case however no reference is acquired and so the error path
might drop a reference the driver isn't holding. Fix that by getting a
reference to the MAC.

Over time, skb recycling infrastructure got litle interest and
many bugs. Generic rx path skb allocation is now using page
fragments for efficient GRO / TCP coalescing, and recyling
a tx skb for rx path is not worth the pain.

Last identified bug is that fat skbs can be recycled
and it can endup using high order pages after few iterations.

With help from Maxime Bizon, who pointed out that commit
87151b86 (net: allow pskb_expand_head() to get maximum tailroom)
introduced this regression for recycled skbs.

Instead of fixing this bug, lets remove skb recycling.

Drivers wanting really hot skbs should use build_skb() anyway,
to allocate/populate sk_buff right before netif_receive_skb()
