What this PR does / why we need it:

The constant math.MaxUint32 has no type specified. Golang tries to cast
it to int, which crashes the assembly on 32 bit architectures.

Steps to reproduce on the current master:

$ GOARCH=386 go build ./cmd/hostpathplugin/main.go
# github.com/kubernetes-csi/csi-driver-host-path/pkg/hostpath
pkg/hostpath/controllerserver.go:663:5: constant 4294967295 overflows int

$ GOARCH=arm go build ./cmd/hostpathplugin/main.go
# github.com/kubernetes-csi/csi-driver-host-path/pkg/hostpath
pkg/hostpath/controllerserver.go:663:5: constant 4294967295 overflows int

Which issue(s) this PR fixes:

Fixes kubernetes-csi/csi-release-tools#167

Hi @c0va23. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
