cros_ec: Correct comparison between signed and unsigned numbers
Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right
thing, since if ec_command() returns a -ve number we will consider this be
success.
Adjust all comparisons to avoid this problem.
This error was found with sandbox, which gives a segfault in this case. On
ARM we may instead silently fail.
We should also consider turning on -Wsign-compare to catch this sort of thing
in future.
