[PULL 14/20] tests: Avoid side effects inside g_assert() arguments

[Thomas Huth <thuth@redhat.com>]

From: 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
