[POWERPC][XEN][TOOLS] Fix a couple of typos

While getting xend/domU up and runngin today I noticed what
look like a couple of typos.

AFAICT do_dom0_op will return 0 or -1, so the failure test in
tools/libxc/powerpc64/xc_memory.c has the wrong operator.

Also in xen/arch/powerpc/shadow.c:shadow_set_allocation() rc is unused
and thus returning stack garbage.
