The enumerate callback doesn't currently iterate through
any hotplugged devices, as it uses an outdated device list
underneath. What updates that list is a bus rescan, which
happens implicitly on DPDK init or a specific device attach.
This wasn't crucial until we refactored NVMe bdev hotplug
poller to use enumerate instead of attach, which broke the
hotplug entirely. Unluckily, the hotplug tests were broken
as well and didn't detect this in time.
We fix the above by rescanning the pci bus before iterating
through its devices inside spdk_pci_enumerate().
