vbdev modules still open/close bdevs as normal, but should open bdevs read only when tasting (i.e. reading the GPT to see if there are SPDK partitions). When a vbdev module is ready to claim the bdev for purposes of creating virtual bdevs on top of it, it calls spdk_vbdev_module_claim_bdev(). It can pass its open descriptor as well to have it promoted to write access (required for future vbdev modules like logical volumes). Note: error vbdev was changed to copy the base bdev parameters one-by-one instead of a blind memcpy - we do not want to copy the base bdev's vbdev_claim_module into the new bdev!
