Block MR cache debugfs creation for IB representor flow as MR cache shouldn't be used
at all in that mode. As part of this change, add missing debugfs cleanup in error path
too.
This change fixes the following debugfs errors:
bond0: (slave enp8s0f1): Enslaving as a backup interface with an up link
mlx5_core 0000:08:00.0: lag map: port 1:1 port 2:1

mlx5_core 0000:08:00.0: Operation mode is single FDB
