Description

Currently, when a user attempts to delete a required mask entry from an ACL, the shell exits with code 1 and prints the error message "Invalid ACL: mask is required, but it was deleted." This has caused some user confusion in testing, because it makes it sound like the delete actually happened and left the ACL in a bad state. Let's change this to "Invalid ACL: mask is required and cannot be deleted."
