MIPS: KASLR: Fix handling of NULL FDT
If platform code returns a NULL pointer to the FDT, initial_boot_params
will not get set to a valid pointer and attempting to find the /chosen
node in it will cause a NULL pointer dereference and the kernel to crash
immediately on startup - with no output to the console.
Fix this by checking that initial_boot_params is valid before using it.
