mlxsw: spectrum_switchdev: Avoid leaking FID's reference count

Browse source

It should never be possible for a user to set a VNI on a FID in case one
is already set. The driver therefore returns an error, but fails to drop
the reference count taken earlier when calling
mlxsw_sp_fid_8021d_lookup().

Drop the reference when this unlikely error is hit.
