tools: kwboot: Do not change received character in kwboot_xm_recv_reply()
Marvell BootROM expects retransmission of previous xmodem packet only in
the case when it sends NAK response to the host.
Do not change non-xmodem response (possibly UART transfer error) to NAK
in kwboot_xm_recv_reply() function. Allow caller to receive original
response from device.
Change argument 'nak_on_non_xm' to 'stop_on_non_xm'. Instead of changing
non-xmodem character to NAK, stop processing on invalid character and
return it.
