[kvm-unit-tests PATCH] s390x: sie: Only overwrite r3 if it isn't needed anymore

[Janosch Frank <frankja@linux.ibm.com>]

The lmg overwrites r3 which we later use to reference the fprs and fpc.
Let's do the lmg at the end where overwriting is fine.

Finding this took me longer than I'd like to admit. :)
