[PULL 05/11] target/ppc/kvm: Replace variable length array in kvmppc_save_htab()

[Thomas Huth <thuth@redhat.com>]

To be able to compile QEMU with -Wvla (to prevent potential security
issues), we need to get rid of the variable length array in the
kvmppc_save_htab() function. Replace it with a heap allocation instead.
