[PATCH] pseries: fix migration-test and pxe-test

[Laurent Vivier <lvivier@redhat.com>]

Commit 29cb4187497d ("spapr: Set VSMT to smp_threads by default")
has introduced a new default value for VSMT that is not supported
by old kernels (before 4.13 kernel) and this breaks "make check"
on these kernels.

To fix that, explicitly set in the involved tests the value that was
used as the default value before the change.
