  No point to waste a vector for cleaning up the leftovers of a moved
interrupt. Aside of that this must be the lowest priority of all vectors
which makes FRED systems utilizing vectors 0x10-0x1f more complicated
than necessary.

Schedule a timer instead.

  x86/vector: Rename send_cleanup_vector() to vector_schedule_cleanup()
  x86/vector: Replace IRQ_MOVE_CLEANUP_VECTOR with a timer callback
