The recently introduced feature that allows 32 bit guests to be
executed under KVM on a 64-bit host incorrectly handles the case
where more than 1 cpu is specified using '-smp N'
For instance, this invocation of qemu
qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2
produces the following error
qemu-system-aarch64: Expected key=value format, found aarch64
which is caused by the destructive parsing performed by
cpu_common_parse_features(), resulting in subsequent attempts
to parse the CPU option string (for each additional CPU) to fail.
So duplicate the string before parsing it, and free it directly
afterwards.
