arm64: kaslr: Reserve size of ARM64_MEMSTART_ALIGN in linear region
When KASLR is enabled (CONFIG_RANDOMIZE_BASE=y), the top 4K of kernel
virtual address space may be mapped to physical addresses despite being
reserved for ERR_PTR values.
Fix the randomization of the linear region so that we avoid mapping the
last page of the virtual address space.
