[Intel-gfx] [PATCH i-g-t v5 14/21] tests/core_hotunplug: Process return values of sysfs operations

[Janusz Krzysztofik]

Return values of driver bind/unbind / device remove/recover sysfs
operations are now ignored.  Assert their correctness.

v2: Add trailing newlines missing from igt_assert messages.
