Nope, the bitmap slot isn't freed until mthca_free().

Now that you mention it, that could be a real problem I guess.
synchronize_irq() isn't enough because the interrupt handler might not
have even started yet.
But on the other hand a CQ can't be destroyed until after all
associated QPs have been destroyed. So could we really miss EQEs for
that long?
