The only user of msi_post_free() - powerpc/pseries - has been changed to
use msi_teardown().
Remove this unused callback.

This patch depends on the powerpc/series conversion patch, which is
currently in powerpc tree:
https://lore.kernel.org/lkml/c7a6d8f27fd217021dea4daad777e81a525ae460.1754903590.git.namcao@linutronix.de/
I think it is most convenient to apply this patch to powerpc tree, if
everyone is okay with that?
