[PATCH] xfs/262: update filter to deal with long device name correctly

[Eryu Guan]

If the device name is too long, the output of xfs_quota -c "df" will be
broke into two lines as

Filesystem           1K-blocks       Used  Available  Use% Pathname
/dev/mapper/rhel_hp--dl388eg8--01-testlv2
                      15718400      32932   15685468    0% /mnt/testarea/scratch
/dev/mapper/rhel_hp--dl388eg8--01-testlv2
                        512000          0     512000    0% /mnt/testarea/scratch/test

and _filter_quota_rpt() couldn't catch the correct available number and
test will fail as

Update the filter so it could catch the correct value.
