mm/memory-failure: remove fsdax_pgoff argument from __add_to_kill

mm/memory-failure: remove fsdax_pgoff argument from __add_to_kill

Patch series "Some cleanups for memory-failure", v3.

A lot of folio conversions, plus some other simplifications.

This patch (of 11):

Unify the KSM and DAX codepaths by calculating the addr in
add_to_kill_fsdax() instead of telling __add_to_kill() to calculate it.
