fanotify.7: Pass array to read(2) directly instead of a pointer to it 

It doesn't make any sense to pass a pointer to the array to
read(2).

It might make sense to pass a pointer to the first element of the
array, but that is already implicitly done when passing the array,
which decays to that pointer, so it's simpler to pass the array.

And anyway, the cast was unneeded, as any pointer is implicitly
cast to `void *`.
