  [PATCH] random32: do not feed jiffies as seed from lpfc driver

  In prandom we have already reseeding mechanisms that trigger
  periodically from a much better entropy source than just
  feeding in jiffies through lpfc_mbx_cmpl_fcf_scan_read_fcf_rec()
  [what a function name 8-)]. Therefore, just remove this.
