mm/hmm.c:hmm_do_fault(): suppress sparse warning

mm/hmm.c:673 hmm_do_fault() error: we previously assumed 'hmm_vma_walk->locked' could be null (see line 654)

Stanislav says this can't happen.  Waste a few cycles to make the warning
go away.

[akpm@linux-foundation.org: WARN_ON_ONCE() if the handler didn't set ->locked, per Stanislav]
