power_supply: Drop usage of nowarn variant of sysfs_create_link()
The function is not exported to modules, plus we do want to catch anyone who tries to create complex hierarchy (in that case we'd need to change 'powers' symlink to a directory, probably under a different name to not break ABI). This patch fixes the following build error: ERROR: "sysfs_create_link_nowarn" [drivers/power/power_supply.ko] undefined!
