[Lkw] [PATCH] nvme-cmb: create an initial stub module

[Marco AR]

Linux modules have init and exit handlers that are called when a module
is loaded and unloaded.  While for a minimal module one of them would
be enough, having only an init handler but not exit one will make the
module unloadable, so we do both.
