extcon: usb-gpio: Don't miss event during suspend/resume

BugLink: https://bugs.launchpad.net/bugs/1826212

commit 04c08008 upstream.

Pin state might have changed during suspend/resume while
our interrupts were disabled and if device doesn't support wakeup.

Scan for change during resume for such case.
