power: supply: apm_power: only unset own apm_get_power_status
[ Upstream commit bd44ea12919ac4e83c9f3997240fe58266aa8799 ]
Mirroring drivers/macintosh/apm_emu.c, this means that
modprobe apm_power && modprobe $anotherdriver && modprobe -r apm_power
leaves $anotherdriver's apm_get_power_status instead of deleting it.
Fixes: 3788ec932bfd ("[BATTERY] APM emulation driver for class batteries")
