[PATCH] nvme: fix build error: nvme_mpath_update stub without static

[Anton Eidelman]

Fix multiple definition of nvme_mpath_update() on
builds with CONFIG_NVME_MULTIPATH disabled:
the stub function is missing "static inline".

Fixes: d50c992edf10 ("nvme-multipath: fix hang when disk goes live over reconnect")
