code-update.md: Call fw_setenv twice for PrepareForUpdate

Support for u-boot redundant environment variables was
added where u-boot alternates writing to each environment
every time a variable is written. But initramfs doesn't
know which environment is active so it always reads from
the same one. Therefore need to twice set the
variables that initramfs reads so that they're written
to both environments and initramfs can read them.
