component/bt : fix bug that there's low ratio crash when BLE do re-connect/re-scan/re-adv

fix 3 bugs:
1. do BLE connect (both of slave and master), it mgiht cause crash due to there's much interrupts happens effect ble code running, for example, wifi run on the same core as bluetooth controller and wifi run throughtput test.
2. do BLE scan stop or adv stop or connection stop, it might cause ASSERT or crash due to memory corrupted in controller memory poll.
3. minor bug fix, not really effect bluetooth.
