ext4: make orphan functions be no-op in no-journal mode

commit c9b92530a723ac5ef8e352885a1862b18f31b2f5 upstream.

Instead of checking whether the handle is valid, we check if journal
is enabled. This avoids taking the s_orphan_lock mutex in all cases
when there is no journal in use, including the error paths where
ext4_orphan_del() is called with a handle set to NULL.
