lib/storage: prevent excessive loops when storage is in RO (#2962) 
* lib/storage: prevent excessive loops when storage is in RO

Returning nil error when storage is in RO mode results
into excessive loops and function calls which could
result into CPU exhaustion. Returning an err instead
will trigger delays in the for loop and save some resources.
