modesetting: Use seq instead of msc in ms_queue_vblank failure path 

When the call to queue a vblank event fails, we need to clean up by
removing the user-space queue entry. That is indexed by the local
sequence number, not by the kernel vblank count. The call in this
case was just passing the wrong value.
