util: log error when closing temp fail fails in GetOMapValue()

Browse Source 
gosec-2.3.0 complains about the following:

    [/go/src/github.com/ceph/ceph-csi/internal/util/cephcmds.go:146] - G307 (CWE-): Deferring unsafe method "*os.File" on type "Close" (Confidence: HIGH, Severity: MEDIUM)
      > defer tmpFile.Close()

By logging the error from Close(), the warning is gone.
