[SCSI] fcoe, libfc: use single frame allocation API
Cleans up frame allocation APIs to have just single fc_frame_alloc API. Removes _fc_frame_alloc, renames __fc_frame_alloc to _fc_frame_alloc. Modifies fc_fcp_send_data for removed _fc_frame_alloc, fc_fcp_send_data was the only user of removed _fc_frame_alloc. Also Adds check in fc_frame_alloc to do mod by 4 for only non-zero len value. This patch is prep work to fix can_queue reducing in next patch. Single fc_frame_alloc API helps in fixing can_queue reducing in next patch.
