Updates fcoe_em_config to allocate a single instance of sharable offload EM for supported lp->lro_xid per eth device, and then share this EM for subsequently more lports creation on same eth device (e.g when using VLAN). Adds tiny fcoe_oem_match function for offload EM to return true for read types IO to have read IO exchanges allocated from offload shared EM. Removes fc_em_alloc_xid function completely which was needed to manage two xid ranges within a EM, this is not needed any more with allocation of separate sharable offload EM per eth device. Instead this patch adds simple xid allocation logic to manage single xid range. Adds fc_exch_em_alloc with mp->next_xid as cursor to allocate new xid from single xid range of EM, uses mp->next_xid instead removed mp->last_xid which slightly increase probability of finding empty xid on exch allocation. Removes restriction of not allowing use of xid zero along with changing two xid range change to single xid range. Makes fc_fcp_ddp_setup calling conditional to only xid allocated from shared offload EM.
