Previously,
1) AP-RO, EC-RO -> checked
2) AP-RW, EC-RO transition to EC-RW -> checked
3) AP-RW, EC-RW already -> NOT checked
Now, (3) calls VbExIsShutdownRequested() as well.
This fix is needed to avoid inconsistent behavior of software sync
after we ship a RW update.
Whether we *should* actually shut down or not based on how/why we
booted is a separate issue to be addressed by the U-boot
implementation of VbExIsShutdownRequested() in a separate CL.
BUG=chromium-os:38645
BRANCH=all
TEST=make runtests
Manual testing also possible - force AP-RW firmware, then reboot with
lid closed. Previously, the first boot would shut down because of
(2), but subsequent reboots of the AP only wouldn't because of (3).
