power: supply: hold extensions_sem when creating LED triggers
LED triggers were created in __power_supply_register without holding the
extensions_sem lock. Since commit b04510c3af6d ("power: supply: leds: create
triggers based on properties, not type") we call power_supply_has_property
during trigger creation and access the extensions there.
Move power_supply_create_triggers down into the lock scope used for
power_supply_add_hwmon_sysfs for the same reason.
Fixes: b04510c3af6d ("power: supply: leds: create triggers based on properties, not type")
