quota: show used_space,(file,dir) count even when quota limit is not set

Problem:
As of now quota 'list/list-objects' will list the usage only if limit is
set for every directory else it will fail with ENOATTR(If inode/inode-quota
is already configured for the first time).

Feature:
With the patch we are enhancing this command to list the usage even
if quota limit is not set but still the user has to configure
inode/inode-quota for the first time.

Example:
Consider we have /client/dir and /client1(absolute path from mount point):
Quota limit is set only on /client. when we try listing /client/dir or /client1,
it shows "Limit not set".

Fix:
The patch fixes this by showing "used space" in case of list command and
shows "file_count" & "dir_count" in case of list-objects command. This works
fine with xml output as well.
