Follow the idea of bdev_get_iostat in module/bdev/rpc/bdev_rpc.c.
Add a global variable g_bdev_count and then set it to 1 as sentinel
value in bdev_construct_targets().
Subsequent patches will make _bdevperf_construct_targets() asynchronous.
Then bdevperf_construct_targets() will be truely asynchronous.
This patch is too small to be an independent patch but keep to
hold previous review result.
