[PATCH] xfs_db: add header to freesp -d output

[Eric Sandeen <sandeen@xxxxxxxxxx>]

Today, xfs_db's freesp -d command dumps out a bunch of numbers:

# xfs_db -c "freesp -d" /dev/sdb1
       0        4        1
       0        5        1
       0        6        1
       0        7        1
       0       12   174772
...

which are not useful to the non-code-reading user.
Add some headers:

# xfs_db -c "freesp -d" /dev/sdb1
    agno    agbno      len
       0        4        1
       0        5        1
       0        6        1
       0        7        1
       0       12   174772
...

so there's at least some context.
