net/mlx5: fix hairpin unbind

Browse Source 
In the implementation of mlx5_hairpin_unbind, a copy-paste error was
inside. If a single peer Rx port needed to be unbound, it would be
bound again by mistake.

All the hardware resources were released when stopping the device and
no mess of the configuration was introduced. But when trying to unbind
the ports again, the issue would appear.

The typo of the function call is fixed. If there is no hairpin queue
bound between two ports, the unbinding process should be considered
successful.

Fixes: 37cd4501e873 ("net/mlx5: support two ports hairpin mode")
