mismatched types int64 and uint32 utils/osutils_linux.go

[scaleoutsean]

Just a small note for Trident enthusiasts who give this a try:

$ GOOS=linux GOARCH=s390x go build
....
# github.com/netapp/trident/utils
utils/osutils_linux.go:70:28: invalid operation: int64(buf.Blocks) * buf.Bsize (mismatched types int64 and uint32)
utils/osutils_linux.go:80:32: invalid operation: int64(buf.Bavail) * buf.Bsize (mismatched types int64 and uint32)

Environment

• Trident source v21.01.1
• Ubuntu Ubuntu 18.04.5 LTS (x86_64)
• go version go1.16 linux/amd64

To Reproduce

Check out source code, install Go, replace gcr.io/distroless/static in 3 Dockerfiles with a link to gcr.io/distroless/static:latest-s390x, build for linux/s390x

Expected behavior

Trident build succeeds

Additional context

On the surface this change to utils/osutils_linux.go helps hide this issue, but I don't know how it impacts the resulting trident image (and have no way to test).
