[Intel-gfx] [PATCH i-g-t v4 10/20] tests/core_hotunplug: Skip selectively on sysfs close errors

[Janusz Krzysztofik]

Since we no longer open a device DRM sysfs node, only a PCI one, driver
unbind operations are no longer affected by missed or unsuccessful
sysfs file close attempts.  Skip only affected subtests if that
happens.

v2: Rebase only.
v3: Refresh.
