tools: logger: fix parsing of -s argument 

Fix logic for saving the snapshot file argument. getopt()
is called at least once after snapshot option is parsed and
getopt() will erase the optarg value when exiting the while
loop. Without this patch, argument is always NULL and snapshot
cannot be taken.
