SX1262: fix serious bug with detecting if we have a rx packet in progress

Browse Source 
Could cause hangs on the way into sleep (and enormous power consumption).
Instead of checking for rx packet length (which only changes at completion)
check if we've received preamble bits but haven't yet received a completed
packet interrupt.

notes:
