lib/vhost: Remove and inline spdk_vhost_blk_get_dev

Browse Source 
Having spdk_vhost_blk_get_dev required us to bump up the SO version
the vhost library when we updated bdev.h but spdk_vhost_blk_get_dev
has not been used publicly, and can be inlined very simply.

So remove spdk_vhost_blk_get_dev from include/spdk/vhost.h and inline
it to the place which had used it.
