msm: camera: Validate gpio calls for LED flash 



If init call for LED flash is missed / failed, gpio_request() may not
be performed for gpio pins for LED flash. This causes stability issues
where gpio calls are performed without gpio_request. Check for valid
client before performing gpio configuration.
