Matthew Wilcox (Oracle) a501a07030 mm: report success more often from filemap_map_folio_range()
Even though we had successfully mapped the relevant page, we would rarely
return success from filemap_map_folio_range().  That leads to falling back
from the VMA lock path to the mmap_lock path, which is a speed &
scalability issue.  Found by inspection.
