This patch drops se_subsystem_api->[write_cache,fua_write]_emulated flags set by viritual FILEIO/IBLOCK/RD_MCP backend drivers in favor of explict TRANSPORT_PLUGIN_PHBA_PDEV checks to know when to fail if userspace is attempting to set virtual emulation bits for an pSCSI (passthrough) backend device.
