[PATCH v3 7/8] pci: fix hotplug operations

[Gaetan Rivet <gaetan.rivet@6wind.com>]

The device handle is already known and does not have to be infered from
the PCI address. The relevant helpers are already available within the
PCI bus to avoid searching for a handle already known.

Additionally, rte_memcpy.h was erroneously included.

Fixes: 00e62aae69c0 ("bus/pci: implement plug/unplug operations")
