usb: phy: gpio-vbus: don't ignore regulator APIs return value
Due to recent changes to regulator API, all users which don't check regulator_{en,dis}able()'s return value will generate compile warnings. Add such checks to gpio-vbus. Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
