[PATCH 01/22] mm: drop unused __mm_flags_set_mask_bits_word()

[Kevin Brodsky]

Commit 39f8049cd49f ("mm: update coredump logic to correctly
use bitmap mm flags") added coredump-specific helpers for the
remaining masked mm-flags update users.

That left __mm_flags_set_mask_bits_word() without any callers.
This is a special-purpose helper that is unlikely to be useful for
other purposes; best to remove it.
