I checked table wp_options and did not find option wp_users, but I found wp_user_roles option. And in values for super_admin I found this:

So what should I change to return to me ability to delete media files? Thank You!

Problem was in advanced access manager plugin. Somehow for super-administrator the button delete have been disappeared but for other role this button is existing. I need to check support in advanced access manager support forum.
