mm: add variant of pagevec_lookup_range_tag() taking number of pages
Currently pagevec_lookup_range_tag() takes number of pages to look up
but most users don't need this. Create a new function
pagevec_lookup_range_nr_tag() that takes maximum number of pages to
lookup for Ceph which wants this functionality so that we can drop
nr_pages argument from pagevec_lookup_range_tag().
