usb: common: usb-conn-gpio: Don't log an error on probe deferral 

commit 59120962e4 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.
