samsung-herolte: fix wifi firmware path (!316)

This patches the path that the kernel tries to load the Wifi chip's
firmware from. If someone with an Galaxy S7 Edge would test this -
although I have no reason to believe that it would not work on the Edge
- then this patch could also be applied to the linux-samsung-hero2lte
package.
