Michael Pratt 02b7b77332 ath79: set lzma-loader variables to null by default
This fixes a small regression where the lzma-loader variable values
are being shared between boards that require different configurations.

If not set to "" globally, a device without these settings will just take
the last values another device has set before in the queue.

Fixes: 1b8bd17c2d ("ath79: lzma-loader: allow setting custom kernel magic")
