libceph: fix legacy layout decode with pool 0
If your data pool was pool 0, ceph_file_layout_from_legacy()
transform that to -1 unconditionally, which broke upgrades.
We only want do that for a fully zeroed ceph_file_layout,
so that it still maps to a file_layout_t. If any fields
are set, though, we trust the fl_pgpool to be a valid pool.
