extmod/modbluetooth: Fix race between READ_REQUEST and other IRQs.
The READ_REQUEST callback is handled as a hard interrupt (because the BLE
stack needs an immediate response from it so it can continue) and so calls
to Python require extra protection:
- the caller-owned tuple passed into the callback must be separate from the
tuple used by other callback events (which are soft interrupts);
- the GC and scheduler must be locked during callback execution.
