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

Browse source 
commit 1c3aa6bd0b upstream.

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")
