quota : volume-reset shouldn't remove quota-deem-statfs

Volume-reset shouldn't remove quota-deem-statfs, unless
explicitly specified, when quota is enabled.

1) glusterd_op_stage_reset_volume ()
   'gluster volume set/reset <VOLNAME>' features.quota/
   features.inode-quota' should not be allowed as it is deprecated.
   Setting and resetting quota/inode-quota features should be allowed
   only through 'gluster volume quota <VOLNAME> enable/disable'.

2) glusterd_enable_default_options ()
   Option 'features.quota-deem-statfs' should not be turned off
   with 'gluster volume reset <VOLNAME>', since quota features
   can be set/reset only with 'gluster volume quota <VOLNAME>
   enable/disable'.

But, 'gluster volume set features.quota-deem-statfs'
can be turned on/off when quota is enabled.

        Backport of http://review.gluster.org/#/c/11839/
