Added missing error check that could cause kubelet to crash **What this PR does / why we need it**: Adds missing error check. An error can happen due to a race condition when watched files change, or become inaccessible. This can happen if a file was added to the driver directory then quickly removed, in which case the callback will be called with non-nil `err` and nil `info`, which is not checked, causing kubelet to crash. **Which issue(s) this PR fixes**: Fixes #60861 **Special notes for your reviewer**: **Release note**: ```release-note NONE ```
