linux: enable NVMe Multipath
Enable NVME_MULTIPATH so that a single /dev/nvmeXnY device will show up for each NVMe namespaces, even if it is accessible through multiple controllers. Can be disabled at boot with `nvme_core.multipath=0`. This is default enabled in Debian [1], Ubuntu 20.04 [2] , Arch [3] and Fedora 33 [4].
