Always start bdev pollers on the calling core. This removes the lcore concept from the bdev poller abstraction and simplifies the job of spdk_bdev_initialize() callers providing their own poller and event implementations. All callers except the NVMe bdev hotplug poller already used the current core as the parameter. The NVMe HotplugPollCore option was undocumented and unused in any of the tests or example configuration files, so it should be safe to remove.
