leds: leds-qpnp: check if flash_wa regulator is obtained before enabling

The flash led requires the use of an optional regulator, "flash_wa_reg".
This regulator is enabled without checking if the regulator is obtained
or not. Hence, a check is made before enabling/disabing the regulator to
ensure that the "flash_wa_reg" is obtained first.
