Subject: [PATCH] md/raid1: fix build breakage

Fix this build error:

  drivers/md/raid1.c: In function 'raid1_congested':
  drivers/md/raid1.c:589: error: 'BDI_write_congested' undeclared

BDI_write_congested was changed in commit 1faa16d228 ("block: change the
request allocation/congestion logic to be sync/async based")
