The bug is caused by using already freed memory.
If there is already an attempt and execute
'reconnect -r' command, all the ConfigFormEntry structure
will be freed in IScsiDriverBindingStop, but the
mCallbackInfo->Current is not configured as null and
this pointer will be used again in IScsiFormExtractConfig.
