[Devel] [PATCH 1/2] dm-qcow2: handle STATUSTYPE_IMA case in dm target status callback

[Alexander Mikhalitsyn]

After 91ccbbac17 ("dm ima: measure data on table load") a new STATUSTYPE_IMA was introduced.
In our case it's fully safe just to return empty data for IMA. We have no any usecases
for it at least now.
