checkstack.pl: fix for aarch64

There is actually a space after "sp," like this, ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]! Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.
