[PATCH v2] ftrace: Clear hashes of stale ips of init memory

Filters should be cleared of init functions during freeing of init memory when the ftrace dyn records are released. However in current code, the filters are left as is. This patch clears the hashes of the saved init functions when the init memory is freed. This fixes the following issue
