xfs: remove quota warning limit from struct xfs_quota_limits

Browse Source 
Warning limits in xfs quota is an unused feature that is currently
documented as unimplemented, and it is unclear what the intended
behavior of these limits are. Remove the ‘warn’ field from struct
xfs_quota_limits and any other related code.
