lightnvm: set default lun range when no luns are specified
The create target ioctl takes a lun begin and lun end parameter, which
defines the range of luns to initialize a target with. If the user does
not set the parameters, it default to only using lun 0. Instead,
defaults to use all luns in the OCSSD, as it is the usual behaviour
users want.
