RDMA/mlx5: Fix wrong free of blue flame register on error 

If the allocation of the fast path blue flame register fails, the driver
should free the regular blue flame register allocated a statement above,
not the one that it just failed to allocate.

Fixes: 16c1975f10 ("IB/mlx5: Create profile infrastructure to add and remove stages")
