Rework of VFS is_offline() function to only return boolean offline/online result for a file.
This makes sense as upper levels are only taking returned result of 0 (no error) into consideration when deciding whether to mark file offline/online as returned from is_offline. That means that we simply can move the decision down to VFS module and clean up upper levels so that they always see only file status. If there is an error when trying to identify file status, then VFS module could decide what to return (offline or online) by itself -- after all, it ought to have system-specific knowledge anyway. (This used to be commit 75cc08661473cce62756fa062071bb2bc1fb39ec)
