kthread_create_on_cpu() sets KTHREAD_IS_PER_CPU and kthread->cpu, this

kthread workers never call kthread_parkme() so this has no effect.

This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
later via a sync_for_cpu or sync_for_device call.

If ll_iget fails during inode initialization, especially
during striped directory lookup after creation failed,
then it should clear stripe MD before make_bad_inode(),
because make_bad_inode() will reset the i_mode, which
can cause ll_clear_inode() skip freeing those stripe MD.

This patch updates the driver code so that we do bulk updates of the page
