Shuhei Matsumoto cad6f55e33 bdev: Add spdk_bdev_get_current_qd to measure and return current value ... The generic bdev layer has a public API spdk_bdev_get_qd() but its value is the most recently measured value and it requires qd sampling to be enabled. We will have bdev modules to want to wait until all bdev_ios are aborted by a reset. Unfortunately, spdk_bdev_get_qd() is not suitable for the custom bdev module. Furthermore, spdk_bdev_channel::io_outstanding is not accessible from bdev modules. Hence, add a new public API spdk_bdev_get_current_qd(). This function should be used only from the bdev module and it should be ensured that the bdev is not unregistered during execution.
