util/nvmutil: don't exit with errno as status

exit with 0 or 1, as is proper.

errno is an int, but the return value on a shell
can be e.g. byte, and depending how that number (errno)
is valued, could overflow and cause a zero exit, where
you want a non-zero exit.

the code has been changed, in such a way to maintain
current behaviour (don't change errno), except that when
errno is set upon exit, the exit value is now one.
