dm: fix unlocked test for dm_suspended_md
In the Linux kernel, the following vulnerability has been resolved: dm: fix unlocked test for dm_suspended_md The function dm_blk_report_zones tests if the device is suspended with the "dm_suspended_md" call. However, this function is called without holding any locks, so the device may be suspended just after it. Move the call to dm_suspended_md after dm_get_live_table, so that the device can't be suspended after the suspended state was tested.
