Subject: [PATCH] Update fthd_ddr.c for Linux Kernel 6.13+ (#304)

* Update fthd_ddr.c

Shipped in linux kernel 6.13, <linux/random.h> no longer includes <linux/prandom.h>. This file depended on that nested include, and this commit changes the include to use that header directly.

Without this, module compilation fails trying to use prandom_seed_state() which is in longer included.

* Update fthd_ddr.c to include linux/random.h in kernels <= 6.12
