[igt-dev] [PATCH i-g-t v2 15/16] tests/core_hotunplug: Explicitly ignore unused return values

Some return values are not useful and can be ignored. Wrap those cases
inside igt_ignore_warn(), not only to make sure compilers are happy but
also to clearly document our decisions.

v2: Rebase on current upstream master.
