librbd/migration/NBDStream: introduce from_nbd_errno()

Errors returned by nbd_get_errno() can't be used to complete Contexts
directly because a) these errors are positive while complete() in most
cases expects a negative error and b) nbd_get_errno() can return 0 even
after libnbd call fails (i.e. returns -1).

Introduce a helper with EIO as a default/fallback error.
