Subject: ACPI: configfs: Add missing config_item_put() to fix refcount leak
From: Hanjun Guo <guohanjun@huawei.com>
commit 9a2e849fb6de471b82d19989a7944d3b7671793c upstream.
config_item_put() should be called in the drop_item callback, to
decrement refcount for the config item.
Fixes: 772bf1e2878ec ("ACPI: configfs: Unload SSDT on configfs entry removal")
