Revert #724e1a7 and replace with stack checks.

Browse source 
Replaces `NimBLEDevice::setConnectionInProgress` and `NimBLEDevice::isConnectionInProgress()` with lower level checks to avoid potential incorrect state reporting.
`NimBLEClient::connect` will instead call `NimBLEScan::stop` if it stopped the scan to release any resources waiting, the call the callback if set.
