ACPI / battery: Safe unregistering of hooks
A hooking API was implemented for 4.17 in fa93854f7a7ed63d followed
by hooks for Thinkpad laptops in 2801b9683f740012. The Thinkpad
drivers did not support the Thinkpad 13 and the hooking API crashes
on unsupported batteries by altering a list of hooks during unsafe
iteration. Thus, Thinkpad 13 laptops could no longer boot.
Additionally, a lock was kept in place and debugging information was
printed out of order.
Fixes: fa93854f7a7e (battery: Add the battery hooking API)
