Currently construct_error_bdev() fails if the base bdev doesn't exist. This patch add configuration of the error vbdev for the base bdev instead, and the configuration will be parsed at examine() when the base bdev is created. This will improve the usability of error injection for bdev and will be usable for the upcoming JSON config file.
