fs: read_mapping_page() should take a struct file argument

Browse Source 
While read_cache_page() takes a void *, because you can pass a
pointer to anything as the first argument of filler_t, if we
are calling read_mapping_page(), it will be passed as the first
argument of ->readpage, so we know this must be a struct file
pointer, and we should let the compiler enforce that for us.
