Mike Snitzer 7676a5b99f dm: interlock pending dm_io and dm_wait_for_bios_completion 
commit 9f6dc63376 upstream.

Commit d208b89401 ("dm: fix mempool NULL pointer race when
completing IO") didn't go far enough.

When bio_end_io_acct ends the count of in-flight I/Os may reach zero
and the DM device may be suspended. There is a possibility that the
suspend races with dm_stats_account_io.

Fix this by adding percpu "pending_io" counters to track outstanding
dm_io. Move kicking of suspend queue to dm_io_dec_pending(). Also,
rename md_in_flight_bios() to dm_in_flight_bios() and update it to
iterate all pending_io counters.

Fixes: d208b89401 ("dm: fix mempool NULL pointer race when completing IO")
