pkg/report: ignore the __alloc_frozen_pages_noprof frame
Even though __alloc_frozen_pages_noprof has the WARN_ON, the actual problem lies in how malloc was called down the stacktrace. This leads to several different bugs being merged into one: https://syzkaller.appspot.com/bug?extid=03fb58296859d8dbab4d Ingore the __alloc_frozen_pages_noprof frame when selecting the bug title.
