[WARNING]: TASK: ... "The loop variable 'item' is already in use." is displayed when calling the role from another role

[berndfinger]

When calling the selinux role from another role and looping over variables, as in https://github.com/sap-linuxlab/community.sap_install/blob/5b920752aa818fcd9fe96ce740bffaa314baf99e/roles/sap_general_preconfigure/tasks/RedHat/generic/configure-selinux.yml#L108 (the task is looping over the list sap_general_preconfigure_sap_directories, which is assigned to the selinux variable selinux_restore_dirs), messages like the following are displayed:

[WARNING]: TASK: fedora.linux_system_roles.selinux : Restore SELinux labels on filesystem tree: The loop variable 'item' is already in use.
You should set the `loop_var` value in the `loop_control` option for the task to something else to avoid variable collisions and unexpected behavior.

As indicated in the warning message, we can avoid this message by replacing item in the selinux role with something else, e.g. line_item, and also adding:

  loop_control:
    loop_var: line_item

to the affected tasks.
