Subject: imsm: FIX: Do not end migration when missing drive is handled

imsm: FIX: Do not end migration when missing drive is handled

Currently when degradation occurs migration is finalized. This is wrong.
Finalizing migration when it is not finished can lead to data corruption
after next array assembly.

Do not finish migration when degradation occurs.
