HID: Input: Add battery list cleanup with devm action
commit 426e5846eba75feaf1c9c6c119cb153610192da1 upstream.
The batteries list (hdev->batteries) is not cleaned up during
hidinput_disconnect(), but struct hid_battery entries are allocated
with devm_kzalloc.
When a driver is unbound (e.g. during devicereprobe), devm frees those
entries while their list_head nodesremain dangling in hdev->batteries,
which persists across rebinds.
