[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.
