docs: path-lookup: remove filename_mountpoint
No filename_mountpoint any more
see commit: commit 161aff1d93ab ("LOOKUP_MOUNTPOINT:
fold path_mountpointat() into path_lookupat()")
Without filename_mountpoint and path_mountpoint(), the
numbers should be four & three:
"These four correspond roughly to the three path_*() functions"
