arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array

In the Linux kernel, the following vulnerability has been resolved:

arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array

The loop that detects/populates cache information already has a bounds
check on the array size but does not account for cache levels with
separate data/instructions cache. Fix this by incrementing the index
for any populated leaf (instead of any populated level).
