nvme: remove multipath module parameter

JIRA: https://issues.redhat.com/browse/RHEL-78133

Upstream Status: RHEL-only

Since device-mapper multipath will no longer be operating on NVMe devices, there is no longer a need for the "multipath" parameter.

Note that, when compiled with CONFIG_NVME_MULTIPATH off multi-path capable controllers and namespaces will continue to present multiple device entries - one for each controller/namespace discovered. This could be confusing, as device-mapper multipath relies upon code in nvme/host/multipath.c, and running device-mapper multipath with a kernel compiled with CONFIG_NVME_MULTIPATH disabled is not supported.
