kernel build error due to large stack frame in __bch2_str_hash_check_key

[Jann Horn]

Hi!

I'm trying to build the mainline kernel at commit
95ec54a420b8f445e04a7ca0ea8deb72c51fe1d3 (upstream git master), but
the build fails with the following error:

```
[...]/fs/bcachefs/str_hash.c: In function ‘__bch2_str_hash_check_key’:
[...]/fs/bcachefs/str_hash.c:295:1: error: the frame size of 2400
bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
  295 | }
      | ^
cc1: all warnings being treated as errors
```

I am building with "gcc (Debian 14.2.0-3+build3) 14.2.0", using the
attached kernel config. I think this used to work with the mainline
kernel before the 6.14 merge window opened.
