target/rd: Allow WriteCacheEnabled=1 operation with rd_mcp backends
This patch adds the missing rd_mcp_template->write_cache_emulated=1 bit to optionally allow WriteCacheEnabled=1 (WCE) to be enabled for the built-in TCM/rd_mcp backend driver. Tested on v3.6-rc[0,2] code with loopback+tcm_vhost fabric ports. Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
