Subject: [PATCH 08/13] DDF: fix detection of failed devices during assembly.
When we call "getinfo_super", we report the working/failed status
of the particular device, and also (via the 'map') the working/failed
status of every other device that this metadata is aware of.
It is important that the way we calculate "working or failed" is
consistent.
As it is, getinfo_super_ddf() will report a spare as "working", but
every other device will see it as "failed", which leads to failure to
assemble arrays with spares.
For getinfo_super_ddf (i.e. for the container), a device is assumed
"working" unless flagged as DDF_Failed.
For getinfo_super_ddf_bvd (for a member array), a device is assumed
"failed" unless DDF_Online is set, and DDF_Failed is not set.
