[SCSI] fcoe, libfc: initialize EM anchors list and then update npiv EMs

EM anchors list initialization for only master port was not enough to
keep npiv working as described here:-
https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html

So this patch moves fc_exch_mgr_list_clone to update npiv ports
EMs once EM anchors list initialized.

Also some cleanup, no need to set lport = NULL as that always
get initialized later.
