Subject: [RHEL7.9 PATCH 64/77] imsm: pass subarray id to kill_subarray
function
After patch b6180160f ("imsm: save current_vol number")
current_vol for imsm is not set and kill_subarray()
cannot determine which volume has to be deleted.
Volume has to be passed as "subarray_id".
The parameter affects only IMSM metadata.
