blob/bdev: Add function pointer get_base_bdev to struct spdk_bs_dev

Browse Source 
spdk_bdev_create_bs_dev_ext() gets not bdev pointer but bdev name
as an argument, and hence vbdev_lvs_create() will get bdev name
accordingly.

However after completing spdk_bdev_create_bs_dev_ext(),
vbdev_lvs_create() has to get bdev pointer from the created bs_dev.

Hence add a function pointer get_base_bdev to struct spdk_bs_dev
and set it to bdev_blob_get_base_bdev() at initialization.
