6ca517d460 nvmf: split subsystem lookup from host check
This allows us to print better error messages when connecting to a
subsystem that exists but does not allow a specific host.

Additionally, we can now return the correct error code for a host that
is not allowed.

6b1e4e732d Drop libpciaccess and switch to DPDK PCI
This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.

Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

Reason: In acceptor_poller_unregistered_event, we
directly call spdk_nvmf_check_pools and spdk_app_stop,
it will fail the memory check.

And function nvmf_delete_subsystem_poller_unreg will
not be called since we already call spdk_app_stop.

plus one terminator byte).
