scsi: fcoe: clear FC_RP_STARTED flags when receiving a LOGO
When receiving a LOGO request we forget to clear the FC_RP_STARTED flag
before starting the rport delete routine.
As the started flag was not cleared, we're not deleting the rport but
waiting for a restart and thus are keeping the reference count of the rdata
object at 1.
This leads to the following kmemleak report:
unreferenced object 0xffff88006542aa00 (size 512):
comm "kworker/0:2", pid 24, jiffies 4294899222 (age 226.880s)
