Incremental: don't be distracted by partition table when calling try_spare. 

Currently a partition table on a device makes "mdadm -I" think
the array has a particular metadata type and so will only
add it to an array of that (partition table) type .. which doesn't
make any sense.

So tell guess_super to only look for 'array' metadata.
