symm/rijndael-arm-crypto.S (rijndael_setup_arm_crypto): Avoid reload.

Juggle the register allocation in the loop which copies over the first
key-data cycle, so as to arrange to leave the last copied key word in
r4.  Then we can elide the explicit load of r4 at the start of the main
key expansion loop, because it already has the right value, saving a
whole instruction.
