usb: common: usb-conn-gpio: Don't log an error on probe deferral
commit 59120962e4be4f72be537adb17da6881c4b3797c upstream.
This patch makes the printout of the error message for failing to get a
VBUS regulator handle conditional on the error code being something other
than -EPROBE_DEFER.
Deferral is a normal thing, we don't need an error message for this.
