[PATCH 3/3] tests: Avoid side effects inside g_assert() arguments

[Peter Maydell <peter.maydell@linaro.org>]

For us, assertions are always enabled, but side-effect expressions
inside the argument to g_assert() are bad style anyway. Fix three
occurrences in IPMI related tests, which will silence some Coverity
nits.

Fixes: CID 1432322, CID 1432287, CID 1432291
