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

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.

# This test checks the project quota values reported by the quota
|
|
# "df" and "report" subcommands to ensure they match what they
|
|
# should be. There was a bug (fixed by xfsprogs commit 7cb2d41b)
|
|
# where the values reported were double what they should have been.
