features/marker: Filter quota xattrs on file as well

Problem:
Quota contributions of a file/directory are tracked by quota
xlator using xattrs on the file. Quota allows these xattrs to be
healed as part of metadata self-heal. This leads to
wrong quota calculations on this brick after self-heal because
quota xattrs don't represent the actual contributions on the
brick anymore.

Fix:
Don't let self-heal of this xattr happen as part of self-heal
by filtering quota xattrs on file in listxattr.
