CVE: NA

--------------------------------

When thinpool is suspended and sets fail_io, resume will report error
as below:
device-mapper: resume ioctl on vg-thinpool  failed: Invalid argument

Thinpool also can't be removed if bio is in deferred list.

This can be easily reproduced using:

  echo "offline" > /sys/block/sda/device/state
  dd if=/dev/zero of=/dev/mapper/thin bs=4K count=1
  dmsetup suspend /dev/mapper/pool
  mkfs.ext4 /dev/mapper/thin
  dmsetup resume /dev/mapper/pool

The root cause is maybe_resize_data_dev() will check fail_io and return
error before called dm_resume.

Fix this by adding FAIL mode check at the end of  pool_preresume().

Fixes: da105ed5 (dm thin metadata: introduce dm_pool_abort_metadata)
