    Display correct type of mdadm recognised ATARAID members (#75)
    
    The previous commit, made mdadm recognised IMSM and DDF type ATARAID
    members get displayed as "linux-raid" (Linux Software RAID array
    member).  This was because of query method 1 in detect_filesystems().
    
    Fix this now by exposing and using the fstype of the member from the
    SWRaid_Info cache.
    
    Closes #75 - Errors with GPT on RAID 0 ATARAID array
