nvme-multipath: pass NS head to nvme_mpath_revalidate_paths()

Browse Source 
In nvme_mpath_revalidate_paths(), we are passed a NS pointer and use that
to lookup the NS head and then use that same NS pointer as an iter variable.

It makes more sense pass the NS head and use a local variable for the NS
iter.
