[SCSI] libfc: Remove FC_FRAME_SG_LEN in fc_fcp_send_data
FC_FRAME_SG_LEN is 4 which is too small when offload is enabled. Actually, the WARN_ON() in fc_fcp_send_data() should be: WARN_ON(skb_shinfo(fp_skb(fp))->nr_frags > MAX_SKB_FRAGS); But since we will not get anything more than 64K anyway, so there is no need to do this anyway here. Therefore, I am getting rid of FC_FRAME_SG_LEN here and the WARN_ON here.
