Subject: regex/mlx5: fix leak on device removal

regex/mlx5: fix leak on device removal

In the removal function, PMD releases all driver resources allocated
in the probe function.

The MR btree memory is allocated in the probe function, but it is not
freed in remove function what caused a memory leak.

Release it.
