Johannes Thumshirn 63d0e3dffd scsi: fcoe: drop frames in ELS LOGO error path

Drop the frames in the ELS LOGO error path instead of just returning an
error.

This fixes the following kmemleak report:
unreferenced object 0xffff880064cb1000 (size 424):
  comm "kworker/0:2", pid 24, jiffies 4294904293 (age 68.504s)
  hex dump (first 32 bytes):
