perf fs: Rename NAME_find_mountpoint() to NAME__mountpoint()

Browse source 
Shorten it, "finding" it is an implementation detail, what callers want
is the pathname, not to ask for it to _always_ do the lookup.

And the existing implementation already caches it, i.e. it doesn't
"finds" it on every call.
