Btrfs: fix the df ioctl to report raid types
Btrfs: fix the df ioctl to report raid types

The new ENOSPC stuff broke the df ioctl since we no longer create seperate space
info's for each RAID type.  So instead, loop through each space info's raid
lists so we can get the right RAID information which will allow the df ioctl to
tell us RAID types again.  Thanks,
