[libvirt] [PATCH] cgroup -Werror fix

[Cole Robinson]

Building with -Werror, I'm getting this error:

make[3]: *** [libvirt_lxc-cgroup.o] Error 1
make[3]: *** Waiting for unfinished jobs....
cc1: warnings being treated as errors
util/cgroup.c: In function 'virCgroupGetMemoryUsage':
util/cgroup.c:743: error: passing argument 4 of 'virCgroupGetValueU64'
from incompatible pointer type
util/cgroup.c:381: note: expected 'long long unsigned int *' but
argument is of type 'uint64_t *'

Patch below fixes it, though I'm not familiar with the code.
