ztest: Add comfort functions for non-zero return codes

Browse source 
Many functions return non-zero return codes on errors. I added an assert
for the case, when a function is expected to fail. It is just a
shorthand for `zassert_not_equal(0, ret);`, analogous to
`zassert_ok`, introduced in c5d85e175f.

I also added the corresponding `zassume_nok` and `zexpect_nok`.
