[kvm-unit-tests PATCH v2 1/3] s390x: smp: move sigp calls with invalid cpu address to array

[Nico Boehr <nrb@linux.ibm.com>]

We have the nice array to test SIGP calls with invalid CPU addresses.
Move the SIGP cases there to eliminate some of the duplicated code in
test_emcall and test_cond_emcall.

Since adding coverage for invalid CPU addresses in the ecall case is now
trivial, do that as well.
