Fix and tidy up debug messages

Debug messages are messed up because cros_ec_invalidate_copy prints
a message with a newline. This patch prevent the debug messages
for the same write or erase operation from being printed in separate
lines.

BUG=none
TEST=Verify flashrom prints the debug messages for each operation
in the same line.
