Keith Busch 69f4eb9ff7 nvme-pci: make CMB SQ mod-param read-only ... A controller reset after a run time change of the CMB module parameter breaks the driver. An 'on -> off' will have the driver use NULL for the host memory queue, and 'off -> on' will use mismatched queue depth between the device and the host. We could fix both, but there isn't really a good reason to change this at run time anyway, compared to at module load time, so this patch makes parameter read-only after after modprobe.
