fix edge-case where bytes_to_read is equal to length of bytes read

Browse source 
rtlsdr_callback would never set do_exit if the length of data read was exactly equal to the remaining bytes_to_read: the first if-block would fail the bytes_to_read < len, but the latter check would decrement bytes_to_read to 0, which would then never subsequently trigger the first block.
