fix: set gid of volume mount point to avoid the issue of time exceeding

[m-anyac]

What type of PR is this?

What this PR does / why we need it:
SetVolumeOwnership function performs a recursive deep walk to change all file permissions, causing a timeout when mounting the pod. Instead of setting gid with the function, this PR fixes the issue by directly setting the gid on the root directory of the volume, which will propagate to all files and directories in NFS share.

Which issue(s) this PR fixes:

Requirements:

Hi @m-anyac. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.
