Fix API break in QuantumCircuit.has_calibration_for
#10427
Conversation
Commit e2674ce (Qiskitgh-10416) reduced usage of the legacy format for `CircuitInstruction` within Terra, but one of the changes meant that a previously valid input to a public API function became invalid. This caused Qiskit Experiments' CI to fail, and wasn't a valid change to Terra.

Should this use find bits? It's the same as before so I'm fine merging it as is, but I just worry the performance of this is pretty poor. Although I guess the number of qubits for a gate won't be that wide so it's probably not a big deal.

Yeah it probably should - this is doing unnecessary linear searches now. I think there's a few places throughout Qiskit where we're doing list.index, and they're pretty much all potential performance problems.

Well lets do all of them in a single pass, the performance here isn't critical for this PR, it's more to fix the api breakage.
