v3dv: remove unnecesary FIXME comment

We only want to cleant BCL barrier flags if we consume a BCL barrier.
For example, if the client records a barrier for an index buffer
it should apply to the next draw call that uses an index buffer
which may not be the current draw call but one coming after it.
