[net-next 10/16] net/mlx5: Pair mutex_destory with mutex_init for rate limit table

[Saeed Mahameed]

From: Parav Pandit <pa...@nvidia.com>

Add missing mutex_destroy() to pair with mutex_init().

This should be done only when table is initialized, hence perform
mutex_init() only when table is initialized.
