Read integrity profile info from top level device.

Browse Source 
When formating device with --integrity-inline option
there's a check if underlying device properly advertise
integrity profile support. The check did not work
properly for partition device nodes. We have to read
integrity profile info from top level block device.

Fixes: #964.
