Commit b43abcbbd5 ("scsi: fnic: Ratelimit printks to avoid flooding when
vlan is not set by the switch.i") added printk_ratelimit() in front of a
couple of debug-mode messages to reduce logging overrun when debugging the
driver. The code:
> if (printk_ratelimit())
> FNIC_FCS_DBG(KERN_DEBUG, fnic->lport->host,
> "Start VLAN Discovery\n");
ends up calling printk_ratelimit() quite often, triggering many kernel
messages about callbacks being supressed.
The fix is to decompose FNIC_FCS_DBG(), then change the order of checks so
that printk_ratelimit() is only called if driver debugging is enabled.
