[-next,21/29] md: use new apis to suspend array for bind_rdev_to_array()

Commit Message

From: Yu Kuai <[e-mail]>

mddev_create_serial_pool() will be called from bind_rdev_to_array(), and
mddev_suspend() will be called if serial pool is used.

Prepare to remove the mddev_suspend() from mddev_create_serial_pool().
