md/raid1: properly indicate failure when ending a failed write request
stable inclusion from linux-4.19.191 commit a6e17cab00fc5bf85472434c52ac751426257c6f -------------------------------- commit 2417b9869b81882ab90fd5ed1081a1cb2d4db1dd upstream. This patch addresses a data corruption bug in raid1 arrays using bitmaps. Without this fix, the bitmap bits for the failed I/O end up being cleared. Since we are in the failure leg of raid1_end_write_request, the request either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded).
