gpio: twl4030: Fix regression for twl gpio LED output
Commit 0b2aa8be introduced a regression that causes failure
in setting LED GPO direction to OUT.
This causes USB host probe failures for Beagleboard C4.
platform usb_phy_gen_xceiv.2: Driver usb_phy_gen_xceiv requests probe deferral
hsusb2_vcc: Failed to request enable GPIO510: -22
reg-fixed-voltage reg-fixed-voltage.0.auto: Failed to register regulator: -22
reg-fixed-voltage: probe of reg-fixed-voltage.0.auto failed with error -22
direction_out/direction_in must return 0 if the operation succeeded.
Also, don't update direction flag and output data if twl4030_set_gpio_direction()
failed inside twl_direction_out();
