Monitor: handle v.quick removal of devices better. 

If a device fails and then is removed before Monitor sees
the failure, GET_DISK_INFO returns nothing so Monitor relies
on mdstat info where '_' is incorrectly interpreted as 'a spare'.

We should treat '_' as 'removed' - that is safer.

Without this, a v.quick fail+remove gets reported as 'Failed' then
'SpareActive'.
