Presently, libmount-mount completely prohibits the use of -t by non-root users. This breaks using -t in listing mode as a user, which represents a regression against mount-deprecated, macosx and presumably *BSD. This commit fixes the issue by deferring the mnt_context_is_restricted check for -t until we know we're not in listing mode.
