ec_sync: always call VbExUpdateAuxFw
call VbExUpdateAuxFw() uncontidionally, instead of when we know we
need to do an update. Vb*AuxFw() already maintains state, so this
doesn't change when we (attempt) to update firmware.
however, this does allow us to iterate over all firmware drivers to
call their .protect() method. previously, we would only call
.protect() after an actual firmware update.
updated unit tests to match the new logic.
BRANCH=none
BUG=b:35585700
TEST=verified i2c tunnels are protected on reef using
ectool i2cprotect N status.
