csi: remove unused NFSDriverName variable

NFSDriverName was assigned once in the CSI controller reconcile but never
read anywhere in the repo (verified with repo-wide grep and an
exported-symbol audit). Remove the variable, its assignment, and the
nfsDriverSuffix const that only existed to feed it.
