quota/marker: turn off inode quotas by default

inode quota is a new feature implemented in glusterfs-3.7
if quota is enabled in the older version and is upgraded
to a new version, we can hit setxattr spike during self-heal
of inode quotas. So, when a quota is enabled, turn off
inode-quotas with a xlator option.

With this patch, we still account for inode quotas but only
when a write operation is performed for a particular file.
User will be able to query inode quotas once the Inode-quota
xlator option is enabled.
