fallback: fix double free of dp

Browse Source 
If the boot option recorded in csv is not in a media device path, the
corresponding full device path will be referred for creating the boot
variable.

However, the current code logic always frees the full device path
(full_device_path) and the media device path (dp) separately. In order
to resolve this issue, always check whether dp equals to full_device_path
before freeing dp.
