net/fungible: Avoid -Wflex-array-member-not-at-end warning

Browse source 
Use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.

So, with these changes, fix the following warning:
drivers/net/ethernet/fungible/funcore/fun_dev.c:550:43: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
