features/marker: Avoid passing structures as parameters to functions

Fixes CIDs: 1388779,1390242,1390057

The patch does the following:

1. Changes the prototype of mq_inspect_file_xattr() and mq_xattr_state()
to have a parameter of struct iatt * instead of struct iatt.
2. Remove unneeded struct iatt parameter from
mq_inspect_directory_xattr()
