grub2: fix some quirks and div by zero

Rather than erroring out on a single attempt while
terminating EFI services, make a few retries because
such quirks are found in a few implementations.
Also fix a div by zero issue in the same framework
which causes an infinite reboot on the target.
Both patches included here are backports.
