4.14-stable review patch. If anyone has any objections, please let me know.

From: "Michael Kelley (EOSG)" <michael.h.kel...@microsoft.com>
[ Upstream commit cabe92a55e3a12005a4ac4d3954c9a174b0efe2a ]
Increase cmd_per_lun to allow more I/Os in progress per device,
particularly for NVMe's. The Hyper-V host side can handle the higher
count with no issues.
