There's a small window during creation of a new RaidLV when rmeta SubLVs are made visible to wipe them in order to prevent erroneous discovery of stale RAID metadata. In case a crash prevents the SubLVs from being committed hidden after such wiping, the RaidLV can still be activated with the SubLVs visible. During deactivation though, a deadlock occurs because the visible SubLVs are deactivated before the RaidLV. The patch adds _check_raid_sublvs to the raid validation in merge.c, an activation check to activate.c (paranoid, because the merge.c check will prevent activation in case of visible SubLVs) and shares the existing wiping function _clear_lvs in raid_manip.c moved to lv_manip.c and renamed to activate_and_wipe_lvlist to remove code duplication. Whilst on it, introduce activate_and_wipe_lv to share with (lvconvert|lvchange).c. Resolves: rhbz1633167 (cherry picked from commit dd5716ddf258c4a44819fa90d3356833ccf767b4) Conflicts: WHATS_NEW lib/activate/activate.c lib/metadata/lv_manip.c lib/metadata/raid_manip.c tools/lvchange.c tools/lvconvert.c
