mm/page_io: remove unneeded ClearPageUptodate() 

Patch series "Convert several functions in page_io.c to use a folio", v4.

Convert several functions in page_io.c to use a folio, which can remove
several implicit calls to compound_head().


This patch (of 10):

The VM_BUG_ON_FOLIO in swap_readpage() ensures that the page is already
!uptodate in __end_swap_bio_read() and sio_read_complete().  Just remove
unneeded ClearPageUptodate().
