net/mlx5e: CT: Fix ct debugfs folder name

[ Upstream commit 849190e3e4ccf452fbe2240eace30a9ca83fb8d2 ]

Need to use sprintf to build a string instead of sscanf. Otherwise
dirname is null and both "ct_nic" and "ct_fdb" won't be created.
But its redundant anyway as driver could be in switchdev mode but
still add nic rules. So use "ct" as folder name.
