Fixed problem with held packet length

According to the xmodem-spec a packet may be 128 or 1024 bytes and can be switched at any time. In order to flush the packet we need to store the received packet length that is held until the next flush.

Disable CR-adding when transferring files via XModem (bdring#528)

* Disable CR-adding when transferring files via XModem

The UART channel have the feature for adding extra CR on line feeds enabled which will break the XModem protocol. This fix will disable the extra CR adding and restore the setting after the file is sent.

* Changed variable name to be consistent with other code.
