Subject: scsi: lpfc: Return early in lpfc_poll_eratt() when the driver is
 unloading
Patch-mainline: v6.8-rc1
Git-commit: 57ea41eb7fe6d6a6bf80f40de9acddb33b41eeb9
References: bsc#1217731

Add a check in lpfc_poll_eratt() when the driver is unloading.  There is no
point to check for error attention events if the driver is rmmod'ed.

If the driver is reloaded, as part of insmod initialization, then a fresh
reset is always asserted to start clean and free of error attention events.
