arm64 calls memblock_free() for the initrd area in its implementation of free_initrd_mem(), but this call has no actual effect that late in the boot process. By the time initrd is freed, all the reserved memory is managed by the page allocator and the memblock.reserved is unused, so the only purpose of the memblock_free() call is to keep track of initrd memory for debugging and accounting. Without the memblock_free() call the only difference between arm64 and the generic versions of free_initrd_mem() is the memory poisoning. Move memblock_free() call to the generic code, enable it there for the architectures that define ARCH_KEEP_MEMBLOCK and use the generic implementation of free_initrd_mem() on arm64.
