Rafael J. Wysocki dae68d7fd4 PCI: hotplug: ACPI: Fix context refcounting in acpiphp_grab_context()
If context is not NULL in acpiphp_grab_context(), but the
is_going_away flag is set for the device's parent, the reference
counter of the context needs to be decremented before returning
NULL or the context will never be freed, so make that happen.

Fixes: edf5bf34d4 ("ACPI / dock: Use callback pointers from devices' ACPI hotplug contexts")
