    bpf, devmap: Remove unnecessary if check in for loop
    
    The iterator variable dst cannot be NULL and the if check can be removed.
    Remove it and fix the following Coccinelle/coccicheck warning reported
    by itnull.cocci:
    
    	ERROR: iterator variable bound on line 762 cannot be NULL
