obsstore: cache size computation for fm1 node
We have two different types of node type (sha1 and sha256, only sha1 is used
now) and therefor different sizes for them. We now compute the value once
instead of redoing the computation every loop. This has no visible performance
impact.

31 with rollback, the other clone will suddenly stop working: all | |
32 operations will fail with "abort: working directory has unknown | |
