cmd/podman/pods: omit superfluous runtime.NumCPU call

sysinfo.NumCPU already falls back to runtime.NumCPU in case the
platform-specific sysinfo.numCPU returns 0, see
https://github.com/containers/common/blob/554799639fc82afeddb9e39ec27a7b85382a6db3/pkg/sysinfo/numcpu.go#L8-L13

Also omit a second call to sysinfo.NumCPU and use the result from the
earlier call.

[NO NEW TESTS NEEDED]
