Subject: [PATCH] bpf: update the comment about the length of analysis

Commit 07016151a446 ("bpf, verifier: further improve search
pruning") increased the limit of processed instructions from
32k to 64k, but the comment still mentioned the 32k limit.
This commit updates the comment to reflect the change.
