[Intel-gfx] [RFC PATH i-g-t 15/15] tests/core_hotunplug: Explicitly ignore unused return values

[Janusz Krzysztofik]

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.
