Fix for #386 (usage of wrong filesystem list)

Wrong fs list used during restore process. Current code uses '/tmp/list_of_fs_objects' which contains all fs of all backuped servers in the DP environment. This is wrong.
Must use the "filtered" list '/tmp/dp_list_of_fs_objects' which contains only the fs for the specific server. 
File is beeing generated in prior script (verify/../50_select_dp_restore.sh).
