[SCSI] fcoe: modifies fcoe_hostlist_lock uses as prep work to add shared offload EM

Browse source

Modifies fcoe_hostlist_lock uses such that a new EM allocation in
fcoe_em_config and adding new fcoe_softc using fcoe_hostlist_add
are atomic, this is to ensure that a shared offload EM gets allocated
only once per eth device for its all lports.
