Subject: objtool warning in ice_free_prof_mask

Hello.

With v6.15-rc1, CONFIG_OBJTOOL_WERROR=y and gcc 14.2.1 the following happens:

```
drivers/net/ethernet/intel/ice/ice.o: error: objtool: ice_free_prof_mask.isra.0() falls through to next function ice_free_flow_profs.cold()
drivers/net/ethernet/intel/ice/ice.o: error: objtool: ice_free_prof_mask.isra.0.cold() is missing an ELF size annotation
```

If I mark ice_write_prof_mask_reg() as noinline, this warning disappears.

Any idea what's going wrong?

Thank you.
