spi_flash: Reload watchdog after erasing each 32K block
A single erase host command may erase an arbitrarily large region of
storage, which may lead to our watchdog firing.
BUG=chrome-os-partner:50587
BRANCH=glados
TEST=Manual on glados, flash RW EC / PD FW while plugging + unplugging
zinger. Verify that watchdog doesn't fire.
