[PATCH u-boot-marvell 07/14] tools: kwboot: Show 'E' in progress output when error occurs

From: Pali Rohár <pali@kernel.org>

When kwboot is unable to resend current xmodem packet, show an 'E' in the
progress output instead of a '+'. This allows to distinguish between the
state when kwboot is retrying sending the packet and when retry is not
possible.
