RISC-V: Fix usage of memblock_enforce_memory_limit
memblock_enforce_memory_limit accepts the maximum memory size not the maximum address that can be handled by kernel. Fix the function invocation accordingly. Fixes: 1bd14a66ee52 ("RISC-V: Remove any memblock representing unusable memory area") Cc: stable@vger.kernel.org Reported-by: Bin Meng <bin.meng@windriver.com> Tested-by: Bin Meng <bin.meng@windriver.com> Acked-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Atish Patra <atish.patra@wdc.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>
