In current version, immidietly following parsing all
metadata pages an action is taken inform of loading the back_bs_dev.
Patches later in the series will add more metadata in form of
extent pages, which have to be read separetly from usual
blob metadata pages.
This patch add separation between the two steps,
so later a device read can be put between.
Additionally, _spdk_blob_load_final() when no snapshot was present
passed bserrno which was always 0. This patch just sets 0 directly
there as no errors occured at that point.
