arm64: adjust KASLR relocation after ARCH_RANDOM removal

Browse Source 
Commit aacd149b62 ("arm64: head: avoid relocating the kernel twice for
KASLR") adds the new file arch/arm64/kernel/pi/kaslr_early.c with a small
code part guarded by '#ifdef CONFIG_ARCH_RANDOM'.

Concurrently, commit 9592eef7c1 ("random: remove CONFIG_ARCH_RANDOM")
removes the config CONFIG_ARCH_RANDOM and turns all '#ifdef
CONFIG_ARCH_RANDOM' code parts into unconditional code parts, which is
generally safe to do.

Remove a needless ifdef guard after the ARCH_RANDOM removal.
