fs: remove unncessary pagevec.h includes

Remove unused pagevec.h includes from .c files. These were found with
the following command:

  grep -rl '#include.*pagevec\.h' --include='*.c' | while read f; do
  	grep -qE 'PAGEVEC_SIZE|folio_batch' "$f" || echo "$f"
  done

There are probably more removal candidates in .h files, but those are
more complex to analyze.
