xfs: call xfs_dquot_set_prealloc_limits if we installed default rtb limits

Browse Source 
Now that we have quotas for the realtime volume, we also have
precomputed watermark limits for the realtime block counts.  These
precomputations should be done any time we change the rtb limits, which
means that xfs_qm_adjust_dqlimits needs to ensure that if we installed
a default rtb limit.
