osd: skip devices marked as '/dev/dead'

On a non-collocated scenario, if a drive is faulty we can't really
remove it from the list of 'devices' without messing up or having to
re-arrange the order of the 'dedicated_devices'. We want to keep this
device list ordered. This will prevent the activation failing on a
device that we know is failing but we can't remove it yet to not mess up
the dedicated_devices mapping with devices.
