[Xen-devel] [PATCH] xl: don't print out uninitialised rc

[Wei Liu <wei.liu2@xxxxxxxxxx>]

In 5b725e56 (xl: improve return and exit codes of vcpu related
functions), the return value of libxl_cpu_bitmap_alloc was not stored in
rc anymore. Yet the subsequent fprintf still used that.

While it is trivial to reinstate the original implementation, xl's
caller has no idea what a libxl error code is so printing out rc won't
be that useful. Don't print out rc in that case.
