client: correct quota check in Client::_rename()

client: correct quota check in Client::_rename()

Client::_rename() only checks for max files quota. As a result, max
bytes quota is not enforced. Thus the following code (copied from
qa/workunits/fs/quota/quota.sh), runs successfully instead of exiting
with error "Disk quota exceeded" -

mkdir files limit
setfattr limit -n ceph.quota.max_bytes -v 1000
truncate filles/file1 -s 1M
mv files limit

This patch makes Client::_rename() enforce both kinds of quota which
leads command "mv files limit" from above script to fail with "Disk
quota exceeded" error. This is the expected behaviour in this case.
